[SimplifyLibCalls] add reflection fold for -sin(-x) (PR38458) This is a very partial fix for the reported problem. I suspect we do not get this fold in most motivating cases because most of the time, the libcall would have been replaced by an intrinsic, and that optimization is handled elsewhere...but maybe it should be handled here? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@339604 91177308-0d34-0410-b5e6-96231b3b80d8
