2ef9c8a43d More consistent thumb1 asm printing.

54c78ef2fe Print VMOV (immediate) operands as hexadecimal values. Apple's assembler 
will not accept negative values for these.  LLVM's default operand printing
sign extends values, so that valid unsigned values appear as negative
immediates.  Print all VMOV immediate operands as hex values to resolve this.

bf16faa16a Implement some hooks, make printOperand abort if unknown modifiers are 
present.

233917c072 add supprort for the 'sbit' operand, MOVi apparently has one.

017d9478d5 implement printSORegOperand, add lowering for the nasty and despicable MOVi2pieces :)

a70e644820 lower the ARM::CONSTPOOL_ENTRY pseudo op, giving us constant pool entries 
like:

@ BB#1:
	.align	2
LCPI1_0:
	.long	L_.str-(LPC0+8)

Note that proper indentation of the label :)

e306d8d6cc add register list and hacked up addrmode #4 support, we now get this: 
_main:
	stmsp! sp!, {r7, lr}
	mov r7, sp
	sub sp, sp, #4
	mov r0, #0
	str r0, [sp]
	ldr r0, LCPI1_0
	bl _printf
	ldr r0, [sp]
	mov sp, r7
	ldmsp! sp!, {r7, pc}

Note the unhappy ldm/stm because of modifiers being ignored.

	str r0, [sp]
	ldr r0, LCPI1_0
	bl _printf
	ldr r0, [sp]

8bc86cba60 wire up some basic printOperand goodness, giving us stuff like this before 
we abort:

_main:
	stm , 
	mov r7, sp
	sub sp, sp, 
	mov r0, 
	str r0,
