No functionality change.

b46443a686 Wire up primitive support in the assembler backend for writing .o files 
directly on the mac.  This is very early, doesn't support relocations and
has a terrible hack to avoid .machine from being printed, but despite
that it generates an bitwise-identical-to-cctools .o file for stuff like 
this:

  define i32 @test() nounwind { ret i32 42 }

I don't plan to continue pushing this forward, but if anyone else was
interested in doing it, it should be really straight-forward.

b7035d0442 split out an encoder for memri operands, allowing a relocation to be plopped 
into the immediate field.  This allows us to encode stuff like this:

        lbz r3, lo16(__ZL4init)(r4)     ; globalopt.cpp:5
                                        ; encoding: [0x88,0x64,A,A]
                                        ;   fixup A - offset: 0, value: lo16(__ZL4init), kind: fixup_ppc_lo16

        stw r3, lo16(__ZL1s)(r5)        ; globalopt.cpp:6
                                        ; encoding: [0x90,0x65,A,A]
                                        ;   fixup A - offset: 0, value: lo16(__ZL1s), kind: fixup_ppc_lo16

With this, we should have a completely function MCCodeEmitter for PPC, wewt.

17e2c18835 add support for encoding the lo14 forms used for a few PPC64 addressing 
modes.  For example, we now get:

	ld r3, lo16(_G)(r3)             ; encoding: [0xe8,0x63,A,0bAAAAAA00]
                                        ;   fixup A - offset: 0, value: lo16(_G), kind: fixup_ppc_lo14

                                        ;   fixup A - offset: 0, value: ha16(__ZL4init), kind: fixup_ppc_ha16

8d70411dcd change direct branches to encode with the same encoding method 
as direct calls.  Change conditional branches to encode with
their own method, simplifying the JIT encoder and making room
for adding an mc fixup.

a9d9ab9673 split call operands out to their own encoding class, simplifying 
code in the JIT.  Use this to form the first fixup for the PPC backend,
giving us stuff like this:

                                        ;   fixup A - offset: 0, value: L_foo$stub, kind: fixup_ppc_br24

5ffe38ef6a 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]

3a4dd305ac 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.

6d2ff122af convert the operand bits into bitfields since they are all combinable in

global values.

1e61e69d40 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.
