b2daeac125 add fields to the .td files unconditionally, simplifying tblgen a bit. 
Switch the ARM backend to use 'let' instead of 'set' with this change.

6f23a467b0 add basic encoding support for immediates and registers, allowing us 
to encode all of these instructions correctly (for example):

        mflr r0                         ; encoding: [0x7c,0x08,0x02,0xa6]
        stw r0, 8(r1)                   ; encoding: [0x90,0x01,0x00,0x08]
        stwu r1, -64(r1)                ; encoding: [0x94,0x21,0xff,0xc0]

d5a087b439 Implement a basic MCCodeEmitter for PPC. This doesn't handle 
fixups yet, and doesn't handle actually encoding operand values,
but this is enough for llc -show-mc-encoding to show the base
instruction encoding information, e.g.:

	mflr r0                         ; encoding: [0x7c,0x08,0x02,0xa6]
	stw r0, 8(r1)                   ; encoding: [0x90,0x00,0x00,0x00]
	stwu r1, -64(r1)                ; encoding: [0x94,0x00,0x00,0x00]
Ltmp0:
	lhz r4, 4(r3)                   ; encoding: [0xa0,0x00,0x00,0x00]
	cmplwi cr0, r4, 8               ; encoding: [0x28,0x00,0x00,0x00]
	beq cr0, LBB0_2                 ; encoding: [0x40,0x00,0x00,0x00]

9ffced5b9d Turn on the new instprinter by default. 
The only change in the output is:

1) we get a better comment on mfcr, we get:
	mfcr r2                         ; cr2
  instead of:
 	mfcr r2 ; 32

2) we no longer emit $stub's on powerpc/leopard.  The Leopard
   linker autosynthesizes them.

e50d695490 convert the operand bits into bitfields since they are all combinable in 
different ways.  Add $non_lazy_ptr support, and proper lowering for
global values.

Now all the ppc regression tests pass with the new instruction printer.

9a0a840839 add targetoperand flags for jump tables, constant pool and block address 
nodes to indicate when ha16/lo16 modifiers should be used.  This lets
us pass PowerPC/indirectbr.ll.

The one annoying thing about this patch is that the MCSymbolExpr isn't
expressive enough to represent ha16(label1-label2) which we need on
PowerPC.  I have a terrible hack in the meantime, but this will have
to be revisited at some point.

Last major conversion item left is global variable references.

a central location. This also makes us a bit more compatible with gas.

3512e07ecf implement support for the MO_DARWIN_STUB TargetOperand flag, 
and have isel apply to to call operands as required.  This allows
us to get $stub suffixes on label references on ppc/tiger with the
new instprinter, fixing two tests.  Only 2 to go.

51168d6510 move the pic base symbol stuff up to MachineFunction 
since it is trivial and will be shared between ppc and x86.
