  Log Message:
  -----------
  [X86] Mark fp128 FMA as LibCall instead of Expand. Add STRICT_FMA as well.

The Expand code would fall back to LibCall, but this makes it
more explicit.

  Log Message:
  -----------
  [X86] Add test cases for most of the constrained fp libcalls with fp128.

Add explicit setOperation actions for some to match their none
strict counterparts. This isn't required, but makes the code
self documenting that we didn't forget about strict fp. I've
used LibCall instead of Expand since that's more explicitly what
we want.

Only lrint/llrint/lround/llround are missing now.
