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.

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]
	beq cr0, LBB0_2                 ; encoding: [0x40,0x00,0x00,0x00]

293ef9ae0f stub out PPCMCInstLowering, add a new option that uses it and the new
instprinter when -enable-ppc-inst-printer is passed to llc.

505ad8bed3 Now that the default for Darwin platforms is to place the LSDA into the TEXT
section, remove the target-specific code that performs this.

53351a175d The same situation that effected ARM effects PPC with regards to placing the
LSDA into the TEXT section. We need to generate non-lazy pointers to it on
Mach-O. However, the object the NLP points to may be local to the translation
unit. If so, then the NLP needs to have the value of that object specified
instead of "0", which the linker interprets as "external".
