[PATCH] D35755: [Solaris] gcc toolchain handling revamp

[Fedor Sergeev via Phabricator via cfe-commits]

fedor.sergeev created this revision.

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.
