Ben Langmuir ce914fc84b Serialization for captured statements
Add serialization for captured statements and captured decls.  Also add
a const_capture_iterator to CapturedStmt.

John McCall f413f5ed44 Move parsing of identifiers in MS-style inline assembly into
the actual parser and support arbitrary id-expressions.

We're actually basically set up to do arbitrary expressions here
if we wanted to.

Assembly operands permit things like A::x to be written regardless
of language mode, which forces us to embellish the evaluation
context logic somewhat.  The logic here under template instantiation
is incorrect;  we need to preserve the fact that an expression was
unevaluated.  Of course, template instantiation in general is fishy
here because we have no way of delaying semantic analysis in the
MC parser.  It's all just fishy.

I've also fixed the serialization of MS asm statements.

This commit depends on an LLVM commit.

Tareq A. Siraj 6dfa25a19f Sema for Captured Statements
Add CapturedDecl to be the DeclContext for CapturedStmt, and perform semantic
analysis. Currently captures all variables by reference.

Tareq A. Siraj 24110cc733 Implement CapturedStmt AST
CapturedStmt can be used to implement generic function outlining as described in
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2013-January/027540.html.

CapturedStmt is not exposed to the C api.

Serialization and template support are pending.

Jordan Rose a7d03840e6 Excise <cctype> from Clang (except clang-tblgen) in favor of CharInfo.h.
Nearly all of these changes are one-to-one replacements; the few that
aren't have to do with custom identifier validation.

Erik Verbruggen 11a2eccc8b Fix for PR12222.
Changed getLocStart() and getLocEnd() to be required for Stmts, and make
getSourceRange() optional. The default implementation for getSourceRange()
is build the range by calling getLocStart() and getLocEnd().

Benjamin Kramer ea70eb30a0 Pull the Attr iteration parts out of Attr.h, so including DeclBase.h doesn't pull in all the generated Attr code.
Required to pull some functions out of line, but this shouldn't have a perf impact.

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.

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.

rather than doing so after the fact. No actual functionality change (yet).
