    A llvm/test/Transforms/InstCombine/simplify-intrinsics.ll

  Log Message:
  -----------
  [SimplifyLibCalls] Shrink sin, cos to sinf, cosf when allowed (#139082)

This optimization already exists, but for the libcall versions of these
functions and not for their intrinsic form.
Solves https://github.com/llvm/llvm-project/issues/139044.

There are probably more opportunities for other intrinsics, because the
switch-case in `LibCallSimplifier::optimizeCall` covers only `pow`,
`exp2`, `log`, `log2`, `log10`, `sqrt`, `memset`, `memcpy` and
`memmove`.
