Douglas Gregor d720daf8bc Make code-completion for Objective-C message sends to "id" work in the 
presence of precompiled headers by forcibly loading all of the
methods we know about from the PCH file before constructing our
code-completion list.

Stuart Hastings c067196984 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.

Daniel Dunbar 3d45e17d15 Driver: Add a Tool::hasGoodDiagnostics hook, and use it to simplify logic for 
deciding when we need to emit an extra "command failed" diagnostic.
 - This also fixes the case where we were emitting that extra diagnostics, even
   when using clang w/ the integrated assembler, which has good diagnostics.

Douglas Gregor 6285f754fa Implement support for code completion of an Objective-C message send to 
"id" or an expression of type "id". In these cases, we produce a list
of all of the (class or instance) methods, respectively, that we know about.

Note that this implementation does not yet work well with precompiled
headers; that's coming soon.

Chris Lattner 3b21e4d404 Give AsmParser an option to control whether it finalizes 
the stream.  New demo:

$ 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

Chris Lattner 8900ef1931 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
$

Chris Lattner adca608281 fix a really nasty bug that Evan was tracking in SCCP. When resolving 
undefs in branches/switches, we have two cases: a branch on a literal
undef or a branch on a symbolic value which is undef.  If we have a
literal undef, the code was correct: forcing it to a constant is the
right thing to do.

If we have a branch on a symbolic value that is undef, we should force
the symbolic value to a constant, which then makes the successor block
live.  Forcing the condition of the branch to being a constant isn't 
safe if later paths become live and the value becomes overdefined.  This
is the case that 'forcedconstant' is designed to handle, so just use it.

This fixes rdar://7765019 but there is no good testcase for this, the
one I have is too insane to be useful in the future.

Daniel Dunbar dc406b8e92 IRgen: Move BitField LValues to just hold a reference to the CGBitFieldInfo. 
- Unfortunately, this requires some horrible code in CGObjCMac which always
   allocats a CGBitFieldInfo because we don't currently build a proper layout
   for Objective-C classes. It needs to be cleaned up, but I don't want the
   bit-field cleanups to be blocked on that.
