1023643d50 relax this test to just check that the lock prefix is encoded properly, 
and to not rely on the register allocator's arbitrary operand choices.

602fc06817 1. merge fast-isel-shift-imm.ll into fast-isel-x86-64.ll 
2. implement rdar://9289501 - fast isel should fold trivial multiplies to shifts
3. teach tblgen to handle shift immediates that are different sizes than the 
   shifted operands, eliminating some code from the X86 fast isel backend.
4. Have FastISel::SelectBinaryOp use (the poorly named) FastEmit_ri_ function
   instead of FastEmit_ri to simplify code.

d8d36e61fd X86: Fix an encoding issue with LOCK_ADD64mr, which could lead to very hard to find miscompiles with the integrated assembler.
