This reverts commit 11d10527852b4d3ed738aa90d8bec0f398160593.
This change is problematic with function pointer template parameters. For
example, building libcxxabi with futexes (-D_LIBCXXABI_USE_FUTEX) produces this
diagnostic:
In file included from .../llvm-project/libcxxabi/src/cxa_guard.cpp:15:

Many of the inputs to clang driver toolchain tools can be things other
than files such as -Xclang and -Xlinker arguments. For now we don't take
such tool pass-through type arguments (although having an -Xifs would be nice to
have to replace things like -emit-merged-ifs). So because for the moment
we are not doing any sort of argument pass-through, I am going to have
InterfaceStubs Merger ignore any non-file type input arguments.

If the lambda used 'this' without without capturing it, an error was
emitted, but the constant evaluator would still attempt to lookup the
capture, and failing to find it, dereference a null pointer.
This only happens in C++17 (as that's when lambdas were made
potentially-constexpr). Therefore, I also updated the
lambda-expressions.cpp test to run in both C++14 and C++17 modes.

Revise the coverage mapping format to reduce binary size by:
1. Naming function records and marking them `linkonce_odr`, and
2. Compressing filenames.
This shrinks the size of llc's coverage segment by 82% (334MB -> 62MB)
and speeds up end-to-end single-threaded report generation by 10%. For
reference the compressed name data in llc is 81MB (__llvm_prf_names).
Rationale for changes to the format:
- With the current format, most coverage function records are discarded.
E.g., more than 97% of the records in llc are *duplicate* placeholders
for functions visible-but-not-used in TUs. Placeholders *are* used to
show under-covered functions, but duplicate placeholders waste space.
- We reached general consensus about giving (1) a try at the 2017 code
coverage BoF [1]. The thinking was that using `linkonce_odr` to merge
duplicates is simpler than alternatives like teaching build systems
about a coverage-aware database/module/etc on the side.
- Revising the format is expensive due to the backwards compatibility
requirement, so we might as well compress filenames while we're at it.
This shrinks the encoded filenames in llc by 86% (12MB -> 1.6MB).
See CoverageMappingFormat.rst for the details on what exactly has
changed.
Fixes PR34533 [2], hopefully.

The addr space qualifier can be added optionally for lambdas after
the attributes. They will alter the default addr space of lambda
call operator that is in generic address space by default for OpenCL.
Syntax:
[ captures ] ( params ) specifiers exception attr opencl_addrspace
-> ret { body }
Example:
[&] (int i) mutable __global { ... };
On the call into lambda a compatibility check will be performed to
determine whether address space of lambda object and its call operator
are compatible. This will follow regular addr space conversion rules
and there will be no difference to how addr spaces work in method
qualifiers.

is finished (PR40006)
This was already the intention of DelayedDllExportClasses, but code such as
this would break it:
template<typename> struct Tmpl {};
struct Outer {
struct Inner {
__declspec(dllexport) Inner() = default;
unsigned int x = 0;
};
Tmpl<Inner> y;
};
ActOnFinishCXXNonNestedClass() would get called when the instantiation of
Templ<Inner> is finished, even though the compiler is still not finished with
Outer, causing the compile fail.
This hooks into Sema::{Push,Pop}ParsingClass() to avoid calling
ActOnFinishCXXNonNestedClass() for template instantiations while a class is
being parsed.

Jenkins sometimes starts a new working directory by appending @2 (or
incrementing the number if the @n suffix is already there). This causes
several clang tests to fail as:
s@INPUT_DIR@%/S/Inputs@g
gets expanded to the invalid:
s@INPUT_DIR@/path/to/workdir@2/Inputs@g
~~~~~~~~~~
where the part marked with ~'s is interpreted as the flags. These are
invalid and the test fails.
Previous fixes simply exchanged the @ character for another like | but
that's just moving the problem. Address it by adding an expansion that
escapes the @ character we're using as a delimiter as well as other magic
characters in the replacement of sed's s@@@.
There's still room for expansions to cause trouble though. One I ran into
while testing this was that having a directory called foo@bar causes lots
of `CHECK-NOT: foo` directives to match. There's also things like
directories containing `\1`

This patch reapplies commit 759948467ea. Patch was reverted due to a
clang-tidy test fail on Windows. The test has been modified. There
are no additional code changes.
Patch was tested with ninja check-all on Windows and Linux.
Summary of code changes:
Clang currently crashes for switch statements inside a template when the
condition is a non-integer field member because contextual implicit
conversion is skipped when parsing the condition. This conversion is
however later checked in an assert when the case statement is handled.
The conversion is skipped when parsing the condition because
the field member is set as type-dependent based on its containing class.
This patch sets the type dependency based on the field's type instead.
This patch fixes Bug 40982.

Emit a gap region beginning where the switch body begins. This sets line
execution counts in the areas between non-overlapping cases to 0.
This also removes some special handling of the first case in a switch:
these are now treated like any other case.
This does not resolve an outstanding issue with case statement regions
that do not end when a region is terminated. But it should address
llvm.org/PR44011.

Currently, when dumping the AST to JSON, the presumed file is what is included
when dumping a source location. This patch changes the behavior to instead dump
the actual file, and only dump a presumed file name when it differs from the
actual file.
This also corrects an issue with the test script generator that would prevent
it from working on Windows due to file permissions issues.

SYCL is single source offload programming model relying on compiler to
separate device code (i.e. offloaded to an accelerator) from the code
executed on the host.
Here is code example of the SYCL program to demonstrate compiler
outlining work:
```
int foo(int x) { return ++x; }
int bar(int x) { throw std::exception("CPU code only!"); }
...
using namespace cl::sycl;
queue Q;
buffer<int, 1> a(range<1>{1024});
Q.submit([&](handler& cgh) {
auto A = a.get_access<access::mode::write>(cgh);
cgh.parallel_for<init_a>(range<1>{1024}, [=](id<1> index) {
A[index] = index[0] + foo(42);
});
}
...
```
SYCL device compiler must compile lambda expression passed to
cl::sycl::handler::parallel_for method and function foo called from this
lambda expression for an "accelerator". SYCL device compiler also must
ignore bar function as it's not required for offloaded code execution.
This patch adds the sycl_kernel attribute, which is used to mark code
passed to cl::sycl::handler::parallel_for as "accelerated code".
Attribute must be applied to function templates which parameters include
at least "kernel name" and "kernel function object". These parameters
will be used to establish an ABI between the host application and
offloaded part.

Since lambdas are represented by callable objects, we add
generic addr space for implicit object parameter in call
operator.
Any lambda variable declared in __constant addr space
(which is not convertible to generic) fails to compile with
a diagnostic. To support constant addr space we need to
add a way to qualify the lambda call operators.

Summary:
This commit adds the `vpselq` intrinsics which take an MVE predicate
word and select lanes from two vectors; the `vctp` intrinsics which
create a tail predicate word suitable for processing the first m
elements of a vector (e.g. in the last iteration of a loop); and
`vpnot`, which simply complements a predicate word and is just
syntactic sugar for the `~` operator.
The `vctp` ACLE intrinsics are lowered to the IR intrinsics we've
already added (and which D70592 just reorganized). I've filled in the
missing isel rule for VCTP64, and added another set of rules to
generate the predicated forms.
I needed one small tweak in MveEmitter to allow the `unpromoted` type
modifier to apply to predicates as well as integers, so that `vpnot`
doesn't pointlessly convert its input integer to an `<n x i1>` before
complementing it.
