1. Don't emit debug info, or other llvm.metadata to the .cbe.c file.
2. Mark static ctors/dtors as such, so that bugpoint works on C++ code
   compiled with the new CFE.

the pointer is known to come from either a global variable, alloca or
malloc.  This allows us to compile this:

  P = malloc(28);
  memset(P, 0, 28);

into explicit stores on PPC instead of a memset call.
