edcc21919f - Support inline asm 'w' constraint for 128-bit vector types. 
- Also support the 'q' NEON registers asm code.

0f885eb7fd Materialize global addresses via movt/movw pair, this is always better 
than doing the same via constpool:
1. Load from constpool costs 3 cycles on A9, movt/movw pair - just 2.
2. Load from constpool might stall up to 300 cycles due to cache miss.
3. Movt/movw does not use load/store unit.
4. Less constpool entries => better compiler performance.

This is only enabled on ELF systems, since darwin does not have needed
relocations (yet).

97a1f550d1 Move DebugInfo checks into EmitComments and remove them from 
target-specific AsmPrinters.  Not all comments need DebugInfo.

58fbf886bb Change Thumb1 address mode printing, instead of 
[r0, #2 * 4]
Now
[r0, #8]

This makes Thumb2 assembly more uniform and frankly the scale doesn't add much.

30095499fc It turns out that the testcase in question uncovered subreg-handling bug. 
Add assert in asmprinter to catch such cases and xfail the tests.
PR is to be filled.

e79354a831 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.

f775e222e0 Print out an informative comment for KILL instructions. 
The KILL pseudo-instruction may survive to the asm printer pass, just like the IMPLICIT_DEF. Print the KILL as a comment instead of just leaving a blank line in the output.

With -asm-verbose=0, a blank line is printed, like IMPLICIT?DEF.

b345825d9e add support for external symbols. The mc instprinter can now handle 
reasonable code like Codegen/ARM/2009-02-27-SpillerBug.ll, producing 
identical output except for superior formatting of constant pool entries.

d7d7fee3fe 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

ec500c80c6 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 :)

through mcinst lowering -> mcinstprinter, when llc is passed
the -enable-arm-mcinst-printer flag.  Currently this
