This makes clang somewhat forward-compatible with new CUDA releases
without having to patch it for every minor release without adding
any new function.
If an unknown version is found, clang issues a warning (can be disabled
with -Wno-cuda-unknown-version) and assumes that it has detected
the latest known version. CUDA releases are usually supersets
of older ones feature-wise, so it should be sufficient to keep
released clang versions working with minor CUDA updates without
having to upgrade clang, too.

-<platform>_version_min flag
In Xcode 11, ld added a new flag called -platform_version that can be used instead of the old -<platform>_version_min flags.
The new flag allows Clang to pass the SDK version from the driver to the linker.
This patch adopts the new -platform_version flag in Clang, and starts using it by default,
unless a linker version < 520 is passed to the driver.

Summary:
On SUSE distributions for 32-bit PowerPC, gcc is configured
as a 64-bit compiler using the GNU triplet "powerpc64-suse-linux",
but invoked with "-m32" by default. Thus, the correct GNU triplet
for 32-bit PowerPC SUSE distributions is "powerpc64-suse-linux"
and not "powerpc-suse-linux".

If a GCC installed is not detected, the driver would default to
the root of the filesystem. This is not ideal when this doesn't
match the install directory of the toolchain and can cause
undesireable behavior such as picking up system libraries or
the system linker when cross-compiling.

Builtins-*-sunos :: compiler_rt_logbf_test.c currently FAILs on Solaris, both SPARC and
x86, 32 and 64-bit.
It turned out that this is due to different behaviour of logb depending on the C
standard compiled for, as documented on logb(3M):
RETURN VALUES
Upon successful completion, these functions return the exponent of x.
If x is subnormal:
o For SUSv3-conforming applications compiled with the c99 com-
piler driver (see standards(7)), the exponent of x as if x
were normalized is returned.
o Otherwise, if compiled with the cc compiler driver, -1022,
-126, and -16382 are returned for logb(), logbf(), and
logbl(), respectively.
Studio c99 and gcc control this by linking with the appropriate version of values-xpg[46].o, but clang uses neither of those.
The following patch fixes this by following what gcc does, as corrected some time ago in
Fix use of Solaris values-Xc.o (PR target/40411)
https://gcc.gnu.org/ml/gcc-patches/2018-01/msg02350.html and

I noticed that clang currently passes --dynamic-linker to ld. This has been the case
since Solaris 11 support was added initially back in 2012 by David Chisnall (r150580).
I couldn't find any patch submission, let alone a justification, for this, and it seems
completely useless: --dynamic-linker is a gld compatibility form of the option, the
native option being -I. First of all, however, the dynamic linker passed is simply the
default, so there's no reason at all to specify it in the first place.
This patch removes passing the option and adjusts the affected testcase accordingly.
Tested on x86_64-pc-solaris2.11 and sparcv9-sun-solaris2.11.

Using noexcept multilib with -fno-exceptions can lead to significant
space savings when statically linking libc++abi because we don't need
all the unwinding and demangling code.
When compiling with ASan, we already get a lot of overhead from the
instrumentation itself, when statically linking libc++abi, that overhead
is even larger.
Having the noexcept variant for ASan can help significantly, we've seen
more than 50% size reduction in our system image, which offsets the cost
of having to build another multilib.

This is a follow up to r361432, changing the layout of per-target
runtimes to more closely resemble multiarch. While before, we used
the following layout:
[RESOURCE_DIR]/<target>/lib/libclang_rt.<runtime>.<ext>
Now we use the following layout:
[RESOURCE_DIR]/lib/<target>/libclang_rt.<runtime>.<ext>
This also more closely resembles the existing "non-per-target" layout:
[RESOURCE_DIR]/lib/<os>/libclang_rt.<runtime>-<arch>.<ext>
This change will enable further simplification of the driver logic
in follow up changes.

This is a follow up to r361432 and r361504 which addresses issues
introduced by those changes. Specifically, it avoids duplicating
file and runtime paths in case when the effective triple is the
same as the cannonical one. Furthermore, it fixes the broken multilib
setup in the Fuchsia driver and deduplicates some of the code.

include/c++
This change is a consequence of the discussion in "RFC: Place libs in
Clang-dedicated directories", specifically the suggestion that
libunwind, libc++abi and libc++ shouldn't be using Clang resource
directory. Tools like clangd make this assumption, but this is
currently not true for the LLVM_ENABLE_PER_TARGET_RUNTIME_DIR build.
This change addresses that by moving the output of these libraries to
lib/$target/c++ and include/c++ directories, leaving resource directory
only for compiler-rt runtimes and Clang builtin headers.

Summary:
This commit moves the logic for determining system, resource and C++
header search paths from CC1 to the driver. This refactor has already
been made for several platforms, but Darwin had been left behind.
This refactor tries to implement the previous search path logic with
perfect accuracy. In particular, the order of all include paths inside
CC1 and all paths that were skipped because nonexistent are conserved
after the refactor. This change was also tested against a code base
of significant size and revealed no problems.

This introduces a support for multilibs to Fuchsia driver. Unlike the
existing multilibs that are used primarily for handling different
architecture variants, we use multilibs to handle different variants
of Clang runtime libraries: -fsanitize=address and -fno-exceptions
are the two we support initially. This replaces the existing support
for sanitized runtimes libraries that was only used by Fuchsia driver
and it also refactors some of the logic to allow sharing between GNU
and Fuchsia drivers.

pass in the -target-sdk-version to the compiler and backend
This commit adds support for reading the SDKSettings.json file in the Darwin
driver. This file is used by the driver to determine the SDK's version, and it
uses that information to pass it down to the compiler using the new
-target-sdk-version= option. This option is then used to set the appropriate
SDK Version module metadata introduced in r349119.
Note: I had to adjust the two ast tests as the SDKROOT environment variable
on macOS caused SDK version to be picked up for the compilation of source file
but not the AST.

Previously we only used target triple as provided which matches the
GCC behavior, but it also means that all clients have to be consistent
in their spelling of target triples since e.g. x86_64-linux-gnu and
x86_64-unknown-linux-gnu will result in Clang driver looking at two
different paths when searching for runtime libraries.
Unfortunatelly, as it turned out many clients aren't consistent in
their spelling of target triples, e.g. many Linux distributions use
the shorter spelling but config.guess and rustc insist on using the
normalized variant which is causing issues. To avoid having to ship
multiple copies of runtimes for different triple spelling or rely on
symlinks which are not portable, we should also check the normalized
triple when constructing paths for multiarch runtimes.

Summary:
The lib paths are not correctly picked up for OpenEmbedded sysroots (like arm-oe-linux-gnueabi) for 2 reasons:
1. OpenEmbedded sysroots are of the form <sysroot>/usr/lib/<triple>/x.y.z. This form is handled in clang but only for Freescale vendor.
2. 64-bit OpenEmbedded sysroots may not have a /usr/lib dir. So they cannot find /usr/lib64 as it is referenced as /usr/lib/../lib64 in clang.
