[LLD] Mark a number of x86 only tests to require x86 Noticed while testing for an out of tree target. There are probably more tests that should be so marked. I'm not sure who owns these tests so I've added a few names I recognise from the recent history. With advice from probinson, ruiu, rafael and dramatically improved by davidb. Thank you all!

# REQUIRES: x86
Add test case for LLD/COFF for stdcall exports in .def files The .def file parser changes I reverted broke this test case, and exported "__imp__foo" instead of "__imp__foo@8". This was http://crbug.com/728726. llvm-svn: 304572

[COFF] Fix the name type for stdcall functions in import libraries Since SVN r303491 and r304573, LLD used the COFFImportLibrary functions from LLVM. These only had two names, Name and ExtName, which wasn't enough to convey all the details of stdcall functions. Stdcall functions got the wrong symbol name in the import library itself in r303491, which is why it was reverted in r304561. When re-landed and fixed in r304573 (after adding a test in r304572), the symbol name itself in the import library ended up right, but the name type of the import library entry was wrong. This had the effect that linking to the import library succeeded (contrary to in r303491, where linking to such an import library failed), but at runtime, the symbol wouldn't be found in the DLL (since the caller linked to the stdcall decorated name).
