    M llvm/test/Transforms/InstCombine/memchr.ll

  Log Message:
  -----------
  [SimplifyLibCalls] Fold memchr() with size 1

If the memchr() size is 1, then we can convert the call into a
single-byte comparison. This works even if both the string and the
character are unknown.

Split off from https://reviews.llvm.org/D122836.
