Teresa Johnson 8068cc68f7 [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.

Benjamin Kramer 96b52c5a6a Mark test as XFAIL instead of disabling it everywhere.
There is no lit feature 'X86' so this test is just disabled completely.
Make it XFAIL until a solution is found.

Mehdi Amini dc4c8cf9ac [LTO] Handles commons in monolithic LTO
The gold-plugin was doing this internally, now the API is handling
commons correctly based on the given resolution.

Teresa Johnson 9ba95f99f3 Restore "Resolution-based LTO API."
This restores commit r278330, with fixes for a few bot failures:
- Fix a late change I had made to the save temps output file that I
  missed due to existing files sitting on my disk
- Fix a bunch of Windows bot failures with "ambiguous call to overloaded
  function" due to confusion between llvm::make_unique vs
  std::make_unique (preface the new make_unique calls with "llvm::")
- Attempt to fix a modules bot failure by adding a missing include
  to LTO/Config.h.

Original change:

Resolution-based LTO API.

Summary:
This introduces a resolution-based LTO API. The main advantage of this API over
existing APIs is that it allows the linker to supply a resolution for each
symbol in each object, rather than the combined object as a whole. This will
become increasingly important for use cases such as ThinLTO which require us
to process symbol resolutions in a more complicated way than just adjusting
linkage.

Patch by Peter Collingbourne.

Teresa Johnson cbf684e6c6 Revert "Resolution-based LTO API."
This reverts commit r278330.

I made a change to the save temps output that is causing issues with the
bots. Didn't realize this because I had older output files sitting on
disk in my test output directory.
