[BuildLibCalls] Use getPtrTy instead of getInt8PtrTy

Stop using getInt8PtrTy() when referring to char* types when
building libcalls. As in many other files we can simply use
getPtrTy() instead, as part of transition into opaque pointers.

This patch is using thing like
  Type *CharPtrTy = B.getPtrTy();
  Type *VoidPtrTy = B.getPtrTy();
in several places, to give the pointer type a name.
The idea is to make the mapping to the libc function prototypes clear.
