[LTO] Fix common test to reflect r279911 and move to X86 subdirectory Adjust the test to reflect the changes to common handling in r279911. This test wasn't running due to an incorrect REQUIRES and thus missed being modified for r279911 before. It was changed to XFAIL when the bad REQUIRES was discovered. Remove the XFAIL and move to a new X86 subdirectory that will properly disable on non-X86. llvm-svn: 280256

[LTO] Fix commons handling Previously the prevailing information was not honored, and commons symbols could override a strong definition. This patch fixes it and propose the following semantic for commons: the client should mark as prevailing the commons that it expects the LTO implementation to merge (i.e. take the maximum size and alignment). It implies that commons are allowed to have multiple prevailing definitions. Differential Revision: https://reviews.llvm.org/D24545 llvm-svn: 281538
