Even after D86621 <https://reviews.llvm.org/D86621>, `clang -m32` on
Solaris/sparcv9 doesn't inline atomics with 8-byte operands, unlike `gcc`.
This leads to many link failures in the testsuite (undefined references to
`__atomic_load_8` and `__sync_val_compare_and_swap_8`. Until a proper
codegen fix can be implemented, this patch works around the first of those
by linking with `-latomic`.
Tested on `sparcv9-sun-solaris2.11`.

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.

- Test needs to be able to handle "clang.exe" on Windows
- Test needs to be able to handle either '/' or '\\' used as the path separator

Summary:
General idea is to utilize generic (mostly Generic_GCC) code
and get rid of Solaris-specific handling as much as possible.
In particular:
- scanLibDirForGCCTripleSolaris was removed, relying on generic
CollectLibDirsAndTriples
- findBiarchMultilibs is now properly utilized to switch between
m32 and m64 include & lib paths on Solaris
- C system include handling copied from Linux (bar multilib hacks)
Fixes PR24606.

This is actually needed, otherwise libc won't be added at all. For
instance when building libclang.so all the libc symbols won't be
found, with ld warning about libc being an "implicit dependency".

This patch refactors the code to use the GCC installation detector
(modified so that it works in Solaris), and uses
ToolChain::GetFilePath everywhere once it works.
