Sanjay Patel 569647fbec [LibCallSimplifier] fold memset(malloc(x), 0, x) --> calloc(1, x) ...

This is a step towards solving PR25892:
https://llvm.org/bugs/show_bug.cgi?id=25892

It won't handle the reported case. As noted by the 'TODO' comments in the patch, 
we need to relax the hasOneUse() constraint and also match patterns that include
memset_chk() and the llvm.memset() intrinsic in addition to memset().
