47131861be 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 :)

c813cf9649 Adjust the scavenge register spilling to allow the target to choose an 
appropriate restore location for the spill as well as perform the actual
save and restore.

The Thumb1 target uses this to make sure R12 is not clobbered while a spilled
scavenger register is live there.

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.

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

d2f263e74f wire up ARM's printMCInst method. Now llvm-mc should be able to produce 
"something" when printing MCInsts, it will just be missing all the 
operand info.

cf8c23d554 remove strings from instructions who are never asmprinted. 
All of these "subreg32" modifier instructions are handled
explicitly by the MCInst lowering phase.  If they got to
the asmprinter, they would explode.  They should eventually
be replace with correct use of subregs.

fdb36c1a29 Clean up the JITResolver stub/callsite<->function maps. 
The JITResolver maps Functions to their canonical stubs and all callsites for
lazily-compiled functions to their target Functions. To make Function
destruction work, I'm going to need to remove all callsites on destruction, so
this patch also adds the reverse mapping for that.

There was an incorrect assumption in here that the only stub for a function
would be the one caused by needing to lazily compile it, while x86-64 far calls
and dlsym-stubs could also cause such stubs, but I didn't look for a test case
that the assumption broke.

This also adds DenseMapInfo<AssertingVH> so I can use DenseMaps instead of
std::maps.
