9d8f002d8f Fix an incorrect logic causing instcombine to miss some _chk -> non-chk transformations.

621f195243 Change VLD1 instructions for loading Q register values to operate on pairs 
of D registers.  Add a separate VLD1q instruction with a Q register
destination operand for use by loadRegFromStackSlot.

d8036fb0de MC: Switch to using MCInst fragments to do relaxation. 
Also, both MCMachOStreamer and MCAssembler are now target independent!
