Chad Rosier 0bca469d11 [ms-inline asm] Have generateAsmString() return the AsmString computed by Sema.
We still need to translate the string, but this at least gets us one step
closer to using the more general EmitAsmStmt() codegen function. No functional
change intended.

Chad Rosier 3dd7bf2c86 [ms-inline asm] Add constraints to MSAsmStmt. We don't currently compute
the constraints, so in the interim we speculatively assume a 'r' constraint.
This is expected to work for most cases on x86.

Richard Smith c202b2809a Add an AttributedStmt type to represent a statement with C++11 attributes
attached. Since we do not support any attributes which appertain to a statement
(yet), testing of this is necessarily quite minimal.

Daniel Dunbar 62ee6417ac [AST/Sema/libclang] Replace getSourceRange().getBegin() with getLocStart().
- getSourceRange().getBegin() is about as awesome a pattern as .copy().size().

I already killed the hot paths so this doesn't seem to impact performance on my
tests-of-the-day, but it is a much more sensible (and shorter) pattern.

Daniel Dunbar b0ab5e9f5c [AST] Reimplement Stmt::getLoc{Start,End} to dispatch to subclass overloads.
- getSourceRange() can be very expensive, we should try to avoid it if at all possible.

In conjunction with the previous commit I measured a ~2% speedup on 403.gcc/combine.c and a 3% speedup on OmniGroupFrameworks/NSBezierPath-OAExtensions.m.

Chandler Carruth a626d645d5 Extend the Stmt AST to make it easier to look through label, default,
and case statements. Use this to make the logic in the CFG builder more
robust at finding the actual statements within a compound statement,
even when there are many layers of labels obscuring it.

Also extend the test cases for a large chunk of PR10063. Still more work
to do here though.

Douglas Gregor e8bbc12152 Extend the ASTContext constructor to delay the initialization of
builtin types (When requested). This is another step toward making
ASTUnit build the ASTContext as needed when loading an AST file,
rather than doing so after the fact. No actual functionality change (yet).

John McCall 4db5c3c83a In ARC, reclaim all return values of retainable type, not just those
where we have an immediate need of a retained value.

As an exception, don't do this when the call is made as the immediate
operand of a __bridge retain.  This is more in the way of a workaround
than an actual guarantee, so it's acceptable to be brittle here.

Chris Lattner 93ede02045 add one more case of mismatched input/output constraints.
When the mismatch is due to a larger input operand that is
a constant, truncate it down to the size of the output.  This
allows us to accept some cases in the linux kernel and elsewhere.
Pedantically speaking, we generate different code than GCC, though
I can't imagine how it would matter:

Clang:
	movb	$-1, %al
	frob %al

GCC:

	movl	$255, %eax
	frob %al

Chris Lattner c8e630e4db Step #1/N of implementing support for __label__: split labels into
LabelDecl and LabelStmt.  There is a 1-1 correspondence between the
two, but this simplifies a bunch of code by itself.  This is because
labels are the only place where we previously had references to random
other statements, causing grief for AST serialization and other stuff.

This does cause one regression (attr(unused) doesn't silence unused
label warnings) which I'll address next.

This does fix some minor bugs:
1. "The only valid attribute " diagnostic was capitalized.
2. Various diagnostics printed as ''labelname'' instead of 'labelname'
3. This reduces duplication of label checking between functions and blocks.

Review appreciated, particularly for the cindex and template bits.
