efd74a0159 The instruction combining pass removes dead instructions, there is no need 
to run the die pass after it.

9401deb320 A pass that uses the generic CodeExtractor to rip out *every* loop in every 
function, as long as the loop isn't the only one in that function. This should
help debugging passes easier with BugPoint.

2eae379388 My previous commit broke the jit. The shift instructions always take 
an 8-bit immediate. So mark the shifts that take immediates as taking
an 8-bit argument. The rest with the implicit use of CL are marked
appropriately.

A bug still exists:

def SHLDmri32  : I2A8 <"shld", 0xA4, MRMDestMem>, TB;           // [mem32] <<= [mem32],R32 imm8

The immediate in the above instruction is 8-bit but the memory
reference is 32-bit. The printer prints this as an 8-bit reference
which confuses the assembler. Same with SHRDmri32.
