Benjamin Kramer fd4777c046 Teach MemoryBuiltins and InstructionSimplify that operator new never returns NULL. ...

This is safe per C++11 18.6.1.1p3: [operator new returns] a non-null pointer to
suitably aligned storage (3.7.4), or else throw a bad_alloc exception. This
requirement is binding on a replacement version of this function.

Brings us a tiny bit closer to eliminating more vector push_backs.
