Arch-specific tests in arch-specific directories

[Renato Golin via llvm-commits]

Hi George,

Please, always remember to move arch-specific tests into arch-specific
directories, as detailed in:

http://llvm.org/docs/TestingGuide.html#platform-specific-tests

or you'll get errors like:

llvm-mc: : error: unable to get target for 'x86_64-pc-linux', see
--version and --triple.

as in:

http://lab.llvm.org:8011/builders/clang-cmake-aarch64-39vma/builds/5909
http://lab.llvm.org:8011/builders/clang-cmake-aarch64-42vma/builds/6633
http://lab.llvm.org:8011/builders/clang-cmake-aarch64-quick/builds/5684
http://lab.llvm.org:8011/builders/clang-cmake-thumbv7-a15/builds/6395
http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15/builds/6404

I have done so in r301176, but I'm surprised you didn't get any of
those emails, as the first one was 2 hours ago.

cheers,
