Benjamin Kramer 6b96fe7e14 InstCombine: Turn umul_with_overflow into mul nuw if we can prove that it cannot overflow. 
This happens a lot in clang-compiled C++ code because it adds overflow checks to operator new[]:
  unsigned *foo(unsigned n) { return new unsigned[n]; }
We can optimize away the overflow check on 64 bit targets because (uint64_t)n*4 cannot overflow.
