[InstCombine] canonicalize fneg with llvm.sin

This is a follow-up to rL339604 which did the same transform
for a sin libcall. The handling of intrinsics vs. libcalls
is unfortunately scattered, so I'm just adding this next to
the existing transform for llvm.cos for now.

This should resolve PR38458:
https://bugs.llvm.org/show_bug.cgi?id=38458
If the call was already negated, the negates will cancel
each other out.

[InstCombine] add tests for llvm.sin(-x); NFC

Also add a corresponding test for llvm.cos with FMF to 
make sure that was handled correctly.
