ee9c595885 Fix PR6019. A load has more than one use if it feeds a bitconvert that 
has more than one use.

23cdb0bdcf DEBUG_VALUE is now variable sized, as it has a 
target-dependent memory address representation in it.
Restore X86 printing of DEBUG_VALUE; lowering is
done in X86RegisterInfo using the normal algorithm.

3752d2fe34 Revert 93499. After discussion with Chris we agreed 
FrameIndexes should be lowered, but the same way as
everything else (target dependent) rather than in a
special hacked way.  The lowering needs to be done
for eventual purposes of Dwarf generation.

9898671a74 Split the TargetAsmParser "ParseInstruction" interface in half: 
the new ParseInstruction method just parses and returns a list of
target operands.  A new MatchInstruction interface is used to
turn the operand list into an MCInst.

This requires new/deleting all the operands, but it also gives 
targets the ability to use polymorphic operands if they want to.

09bf003983 ARM "l" constraint for inline asm means R0-R7, also for Thumb2. 
This is consistent with llvm-gcc's arm/constraints.md.

Certain instructions (e.g. CBZ, CBNZ) require a low register, even in Thumb2
mode.

069e100f9a Don't fold insufficiently aligned ldr/str into ldm/stm instructions. 
An unaligned ldr causes a trap, and is then emulated by the kernel with
awesome performance. The darwin kernel does not emulate unaligned ldm/stm
Thumb2 instructions, so don't generate them.

This fixes the miscompilation of Multisource/Applications/JM/lencod for Thumb2.

Generating unaligned ldr/str pairs from a 16-bit aligned memcpy is probably
also a bad idea, but that is beyond the scope of this patch.
