add new concrete versions for 1/2/4-byte mergable strings.

These are not actually created yet.

817618d570 Emit sub r, #c instead of transforming it to add r, #-c if c fits in 8-bit. This is a bit of pre-mature optimization. 8-bit variant makes it likely it will be narrowed to a 16-bit instruction.

52a40f9b97 Propogate the Depth argument when calling 
TLI.computeMaskedBitsForTargetNode from ComputeMaskedBits, since
the former may call back into the latter. This fixes a major

in a particularly bad way, PR4643.

1b274fd5f0 Fix Bug 4657: register scavenger asserts with subreg lowering 
When LowerSubregsInstructionPass::LowerInsert eliminates an INSERT_SUBREG
instriction because it is an identity copy, make sure that the same registers
are alive before and after the elimination.

When the super-register is marked <undef> this requires inserting an
IMPLICIT_DEF instruction to make sure the super register is live.

Fix a related bug where a kill flag on the inserted sub-register was not transferred properly.

Finally, clear the undef flag in MachineInstr::addRegisterKilled. Undef implies dead and kill implies live, so they cant both be valid.

af54b9b643 Make SimplifyDemandedUseBits generate vector constants where

that actually fails.

21c4f86d86 Change C, CBE, MSIL to not provide target data via getTargetData(). 
- The theory is these should never actually be called, since these boil down to
   passes which can access the target data via the standard mechanism.
