  Log Message:
  -----------
  [X86] Add tests for constrained float intrinsics on i686-pc-windows-msvc. NFC

We need to promote these to double due to missing libcalls on
Windows.

  Log Message:
  -----------
  [X86][FPEnv] Promote some float strictfp operations to double on i686-pc-windows-msvc to match what we do for non-strict.

The float libcalls are inlined in MSVC's math header where they
just cast to double and use the double libcall. Do the same when
we emit libcalls.
