0d883e3f84 sink handling of target-independent machine instrs (other 
than DEBUG_VALUE :(  ) into the target indep AsmPrinter.cpp
file.   This allows elimination of the 
NO_ASM_WRITER_BOILERPLATE hack among other things.

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 :)

306d14f9aa handle addmode4 modifiers, fix a fixme in printRegisterList 
by ignoring all implicit regs when lowering.

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.

084f87d445 add addrmode2 support, getting us up to: 
_main:
	stm , 
	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
	ldm ,

6f99776f6c add jump tables, constant pools and some trivial global 
lowering stuff.  We can now compile hello world to:

_main:
	stm , 
	mov r7, sp
	sub sp, sp, #4
	mov r0, #0
	str r0, 
	ldr r0, 
	bl _printf
	ldr r0, 
	mov sp, r7
	ldm , 

Almost looks like arm code :)

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

	mov r0, 
	str r0,
