Our build system does not handle randomly named files created during
the build well. We'd prefer to write compilation output directly
without creating a temporary file. Function parameters already
existed to control this behavior but were not exposed all the way out
to the command line.

The driver actually adds a default -mlinker-version, based on HOST_LINK_VERSION
cmake variable. The tests should be explicit about which version they're using to
trigger the right behavior.

-<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.

GCC implicitly adds an .exe suffix if it is given an output file name,
but the file name doesn't contain a suffix, and there are certain
users of GCC that rely on this behaviour (and run into issues when
trying to use Clang instead of GCC). And MSVC's cl.exe also does the
same (but not link.exe).
However, GCC only does this when actually running on windows, not when
operating as a cross compiler.
As GCC doesn't have this behaviour when cross compiling, we definitely
shouldn't introduce the behaviour in such cases (as it would break
at least as many cases as this fixes).

-fno-use-init-array rules
D39317 made clang use .init_array when no gcc installations is found.
This change changes all gcc installations to use .init_array .
GCC 4.7 by default stopped providing .ctors/.dtors compatible crt files,
and stopped emitting .ctors for __attribute__((constructor)).
.init_array should always work.
FreeBSD rules are moved to FreeBSD.cpp to make Generic_ELF rules clean.

Very few ELF platforms still use .ctors/.dtors now. Linux (glibc: 1999-07),
DragonFlyBSD, FreeBSD (2012-03) and Solaris have supported .init_array
for many years. Some architectures like AArch64/RISC-V default to
.init_array . GNU ld and gold can even convert .ctors to .init_array .
It makes more sense to flip the CC1 default, and only uses
-fno-use-init-array on platforms that don't support .init_array .
For example, OpenBSD did not support DT_INIT_ARRAY before Aug 2016
(https://github.com/openbsd/src/commit/86fa57a2792c6374b0849dd7b818a11e676e60ba)
I may miss some ELF platforms that still use .ctors, but their
maintainers can easily diagnose such problems.

Serialized remarks contain debug locations for each remark, by storing a
file path, a line, and a column.
Also, remarks support being embedded in a .dSYM bundle using a separate
section in object files, that is found by `dsymutil` through the debug
map.
In order for tools to map addresses to source and display remarks in the
source, we need line tables, and in order for `dsymutil` to find the
object files containing the remark section, we need to keep the debug
map around.

Summary:
The HIP toolchain invokes `llc` without an explicit opt-level, meaning
it always uses the default (-O2). This makes it impossible to use -O1,
for example. The HIP toolchain also coerces -Os/-Oz to -O2 even when
invoking opt, and it coerces -Og to -O2 rather than -O1.
Forward the opt-level to `llc` as well as `opt`, and only coerce levels
where it is required.

clang test Driver/darwin-opt-record.c assumes the default target is
x86_64 by its uses of the -arch x86_64 and -arch x86_64h and thus fail
on systems where it is not the case. Adding a target
x86_64-apple-darwin10 reveals another problem: the driver refuses 2
-arch for an assembly output so this commit also changes the output to
be an object file.

In the GNU toolchain, `-static-libgcc` implies that the unwindlib will
be linked statically. However, when `--unwindlib=libunwind`, this flag is
ignored, and a bare `-lunwind` is added to the linker args. Unfortunately,
this means that if both `libunwind.so`, and `libunwind.a` are present
in the library path, `libunwind.so` will be chosen in all cases where
`-static` is not set.
This change makes `-static-libgcc` affect the `-l` flag produced by
`--unwindlib=libunwind`. After this patch, providing
`-static-libgcc --unwindlib=libunwind` will cause the driver to explicitly
emit `-l:libunwind.a` to statically link libunwind. For all other cases
it will emit `-l:libunwind.so` matching current behavior with a more
explicit link line.

There doesn't seem to be much sense in defaulting "on" unwind tables on
amd64 and not on other arches. It causes surprising differences between
platforms, such as the PR below[1].
Prior to this change, FreeBSD inherited the default implementation of the
method from the Gnu.h Generic_Elf => Generic_GCC parent class, which
returned true only for amd64 targets. Override that and opt on always,
similar to, e.g., NetBSD's driver.

Summary:
Clang/LLVM is a cross-compiler, and so we don't have to make a choice
about `-march`/`-mabi` at build-time, but we may have to compute a
default `-march`/`-mabi` when compiling a program. Until now, each
place that has needed a default `-march` has calculated one itself.
This patch adds a single place where a default `-march` is calculated,
in order to avoid calculating different defaults in different places.
This patch adds a new function `riscv::getRISCVArch` which encapsulates
this logic based on GCC's for computing a default `-march` value
when none is provided. This patch also updates the logic in
`riscv::getRISCVABI` to match the logic in GCC's build system for
computing a default `-mabi`.
This patch also updates anywhere that `-march` is used to now use the
new function which can compute a default. In particular, we now
explicitly pass a `-march` value down to the gnu assembler.
GCC has convoluted logic in its build system to choose a default
`-march`/`-mabi` based on build options, which would be good to match.
This patch is based on the logic in GCC 9.2.0. This commit's logic is
different to GCC's only for baremetal targets, where we default
to rv32imac/ilp32 or rv64imac/lp64 depending on the target triple.
Tests have been updated to match the new logic.
