Rainer Orth d39a9e3b4d [Driver] Support GNU ld on Solaris 
This patch supports GNU ld on Solaris in addition to Solaris ld, the
default.

- Linker selection is dynamic: one can switch between Solaris ld and GNU ld
  at runtime, with the default selectable with `-DCLANG_DEFAULT_LINKER`.

- Testcases have been adjusted to test both variants in case there are
  differences.

- The `compiler-rt/cmake/config-ix.cmake` and
  `llvm/cmake/modules/AddLLVM.cmake` changes to restrict the tests to
  Solaris ld are necessary because GNU accepts unknown `-z` options, but
  warns every time they are used, creating a lot of noise.  Since there
  seems to be no way to check for those warnings in
  `llvm_check_compiler_linker_flag` or `llvm_check_compiler_linker_flag`, I
  restrict the cmake tests to Solaris ld in the first place.

- The changes to `clang/test/Driver/hip-link-bundle-archive.hip` and
  `flang/test/Driver/linker-flags.f90` are required when LLVM is built with
  `-DCLANG_DEFAULT_LINKER=gld` on Solaris: `MSVC.cpp`
  `visualstudio::Linker::ConstructJob` ultimately calls
  `GetProgramPath("gld")`, resulting in a search for `gld`, which exists in
  `/usr/bin/gld` on Solaris.  With `-fuse-ld=`, this doesn't happen and the
  expected `link` is returned.

- `compiler-rt/test/asan/TestCases/global-location-nodebug.cpp` needs to
  enforce the Solaris ld, otherwise the test would `XPASS` with GNU ld
  which has the `-S` semantics expected by the test.

Tested on `amd64-pc-solaris2.11` and `sparcv9-sun-solaris2.11` with both
`-DCLANG_DEFAULT_LINKER=gld` and the default, and `x86_64-pc-linux-gnu`.
No regressions in either case.
