76c564b1bb change a ton of code to not implicitly use the "O" raw_ostream 
member of AsmPrinter.  Instead, pass it in explicitly.

86d61b5837 start moving towards emitting inline asm statements with 
EmitInlineAsm.  However, this attempt is foiled by operands
being emitted directly to "O" so I'll have to do some surgery
and finish MCizing the world.

8a87fb7633 add a new EmitInlineAsm function to asmprinter to handle inline asm. 
If we have an MCAsmStreamer, we continue to emit asm textually, 
otherwise we (currently) emit an error to errs and ignore it.

915c5f9862 Switch the code generator (except the JIT) onto the new DebugLoc 
representation.  This eliminates the 'DILocation' MDNodes for 
file/line/col tuples from -O0 -g codegen.

This remove the old DebugLoc class, making it a typedef for DebugLoc,
I'll rename NewDebugLoc next.

I didn't update the JIT to use the new apis, so it will continue to
work, but be as slow as before.  Someone should eventually do this
or, better yet, rip out the JIT debug info stuff and build the JIT
on top of MC.

9897043928 Rip out the 'is temporary' nonsense from the MCContext interface to 
create symbols.  It is extremely error prone and a source of a lot
of the remaining integrated assembler bugs on x86-64.

This fixes rdar://7807601.

bd477bef25 Refactor code to push DILocation prcessing into DwarfDebug.cpp from AsmPrinter.cpp.

db035a0af2 Fix the third (and last known) case of code update problems due 
to LLVM IR changes with addr label weirdness.  In the testcase, we
generate references to the two bb's when codegen'ing the first
function:

_test1:                                 ## @test1
	leaq	Ltmp0(%rip), %rax
..
	leaq	Ltmp1(%rip), %rax

Then continue to codegen the second function where the blocks
get merged.  We're now smart enough to emit both labels, producing
this code:

_test_fun:                              ## @test_fun
## BB#0:                                ## %entry
Ltmp1:                                  ## Block address taken
Ltmp0:
## BB#1:                                ## %ret
	movl	$-1, %eax
	ret

Rejoice.

561334a81f Implement support for the case when a reference to a addr-of-bb 
label is generated, but then the block is deleted.  Since the
value is undefined, we just emit the label right after the entry 
label of the function.  It might matter that the label is in the
same section as the function was afterall.

e468f88b26 rearrange MCContext ownership. Before LLVMTargetMachine created it 
and passing off ownership to AsmPrinter.  Now MachineModuleInfo
creates it and owns it by value.  This allows us to use MCSymbols
more consistently throughout the rest of the code generator, and
simplifies a bit of code.  This also allows MachineFunction to 
keep an MCContext reference handy, and cleans up the TargetRegistry
interfaces for AsmPrinters.

        movl    96(%esp), %eax          ## 4-byte Reload
