Gordon Henriksen 7993f4a6d1 PR2202: LLVMCreateInterpreter creates a JIT 
Applying fix by Frits van Bommel.

Evan Cheng 9165e165dc Fix bug in x86 memcpy / memset lowering. If there are trailing bytes not handled by rep instructions, a new memcpy / memset is introduced for them. However, since source / destination addresses are already adjusted, their offsets should be zero.

Evan Cheng 3980a7911a - Check if a register is livein before removing it. It may have already been removed. 
- Do not iterate over SmallPtrSet, the order of iteration is not deterministic.
