Eli Friedman 8b3efeb103 [SimplifyLibCalls] Fix memchr expansion for constant strings. ...

The C standard says "The memchr function locates the first
occurrence of c (converted to an unsigned char)[...]".  The expansion
was missing the conversion to unsigned char.

Fixes https://bugs.llvm.org/show_bug.cgi?id=39041 .
