[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().
