[x86] update fma test with deprecated intrinsics; NFC

Similar to 8854b27b -

All of the CHECK lines should be identical to before,
but without any of the x86-specific calls that were
replaced with generic FMA long ago.

The file still has value because it shows a miscompile
as demonstrated in D90901, but we probably need to
add tests with FMF to make that explicit without
losing coverage.
