393ea6fc22 introduce a new recoverable error handling API to LLVMContext
and use it in one place in inline asm handling stuff.  Before
we'd generate this for an invalid modifier letter:

$ clang asm.c -c -o t.o
fatal error: error in backend: Invalid operand found in inline asm: 'abc incl    ${0:Z}'
INLINEASM <es:abc incl    ${0:Z}>, 10, %EAX<def>, 2147483657, %EAX, 14, %EFLAGS<earlyclobber,def,dead>, <!-1>


Now we generate this:

$ clang asm.c -c -o t.o
error: invalid operand in inline asm: 'incl    ${0:Z}'
asm.c:3:12: note: generated from here
  __asm__ ("incl    %Z0" : "+r" (X));
           ^
1 error generated.

This is much better but still admittedly not great ("why" is the operand 
invalid??), codegen should try harder with its diagnostics :)

dde7376e9d Three changes:
1. Introduce some enums and accessors in the InlineAsm class
   that eliminate a ton of magic numbers when handling inline
   asm SDNode.
2. Add a new MDNodeSDNode selection dag node type that holds
   a MDNode (shocking!)
3. Add a new argument to ISD::INLINEASM nodes that hold !srcloc
   metadata, propagating it to the instruction emitter, which
   drops it.

No functionality change.

749cf45929 Revise debug info machinery to digest nested functions and classes.
A certain GDB testsuite case (local.cc) has a function nested inside a
class nested inside another function.  GCC presents the innermost
function to llvm-convert first.  Heretofore, the debug info mistakenly
placed the inner function at module scope.  This patch walks the GCC
context links and instantiates the outer class and function so the
debug info is properly nested.  Radar 7426545.

5b4c7591ac add .o file writing for inline asm in llc. Here's a silly
demo:

$ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
<inline asm>:1:2: error: unrecognized instruction
	abc incl    %eax
	^
LLVM ERROR: Error parsing inline asm

Only problem seems to be that the parser finalizes OutStreamer 
at the end of the first inline asm, which isn't what we want.
For example:

$ cat asm.c
int foo(int X) {
 __asm__ ("incl    %0" : "+r" (X));
 return X;
}
$ clang asm.c -S -o - -emit-llvm | llc
...
	subq	$8, %rsp
	movl	%edi, (%rsp)
	movl	%edi, %eax
	## InlineAsm Start
	incl    %eax
	## InlineAsm End
	movl	%eax, (%rsp)
	movl	%eax, 4(%rsp)
	addq	$8, %rsp
	ret
$ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
$ otool -tv t.o
t.o:
(__TEXT,__text) section
_foo:
0000000000000000	subq	$0x08,%rsp
0000000000000004	movl	%edi,(%rsp)
0000000000000007	movl	%edi,%eax
0000000000000009	incl	%eax

0d3490e0b0 clean up the asmprinter interface a bit, rename a few
"Print" methods to "Emit".  Emit is something that goes
to an mc streamer, Print is something that goes to a
raw_ostream (for inline asm)

cb654f3113 remove TargetMachine.h #include, also, TRI isn't used frequently
enough to warrant caching in AsmPrinter, so remove it.

3eaaa7bb6c Momentous day: remove the "O" member from AsmPrinter. Now all
"asm printering" happens through MCStreamer.  This also 
Streamerizes PIC16 debug info, which escaped my attention.

This removes a leak from LLVMTargetMachine of the 'legacy'
output stream.

b0eb3e8e49 now that all operand printing happens to specified streams, we can
print function level inline asm with EmitInlineAsm instead of writing
it directly to "O".

1917725796 remove the raw_ostream from various dwarf printing things.
The only thing left is LEB printing, which uses EmitRawText
for now.
