This matches OpenBSD, and it supports Swift's use of clang for its C interop
functionality. Recent changes to Swift use AddClangSystemIncludeArgs() to
inspect the cc1 args; this doesn't work for platforms where cc1 adds standard
include paths implicitly. See:
<cf3354222d>
Also clean up InitHeaderSearch, making it clearer which targets manage header
search paths in the driver.

Based on the discussion at [1], this patch adds a Clang flag called
-fexperimental-library that controls whether experimental library
features are provided in libc++. In essence, it links against the
experimental static archive provided by libc++ and defines a feature
that can be picked up by libc++ to enable experimental features.
This ensures that users don't start depending on experimental
(and hence unstable) features unknowingly.

GNU ld has a hack that defaults to -X (--discard-locals) in the emulation file
`riscvelf.em`. The recommended way, as gcc/config/arm does, is to let the
compiler driver pass -X to ld.
(The motivation is likely to discard a plethora of `.L` symbols due to linker
relaxation.)
lld default to --discard-none. To make clang+lld match GNU ld's behavior, pass
-X to ld.
Note: GNU ld has a special rule to treat ld -r -s as ld -r -S -x. With -X, driver `-r -Wl,-s`
will behave as ld `-r -S -X`. This removes fewer symbols than `-r -S -x` but is safe.

The driver uses class SanitizerArgs to store parsed sanitizer arguments. It keeps a cached
SanitizerArgs object in ToolChain and uses it for different jobs. This does not work if
the sanitizer options are different for different jobs, which could happen when an
offloading toolchain translates the options for different jobs.
To fix this, SanitizerArgs should be created by using the actual arguments passed
to jobs instead of the original arguments passed to the driver, since the toolchain
may change the original arguments. And the sanitizer arguments should be diagnose
once.
This patch also fixes HIP toolchain for handling -fgpu-sanitize: a warning is emitted
for GPU's not supporting sanitizer and skipped. This is for backward compatibility
with existing -fsanitize options. -fgpu-sanitize is also turned on by default.

After b18cb9c47, clang would sometimes prefer the host C++ includes
(e.g. in /usr/include/c++/v1) before those specified via --sysroot.
While this behavior may be desirable on Linux, it is not so on FreeBSD,
where we make extensive use of --sysroot during the build of the base
system. In that case, clang must *not* search outside the sysroot,
except for its own internal headers.
Add an override addLibCxxIncludePaths() to restore the old behavior,
which is to simply append /usr/include/c++/v1 to the specified sysroot.
While here, apply clang-format to the FreeBSD specific toolchain files.
Fixes PR44923.

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.
