[PATCH] D19299: lower __builtin_expect() directly to prof metadata instead of LLVM intrinsic

Patch updated:

1. Fixed/removed comments
2. Changed likely/unlikely profile weights to be min/max values. I'm not sure why 4 and 64 were used in LowerExpectIntrinsics, but that may not trigger the programmer's intent with builtin_expect().
