Chris Lattner c02c4abe5b Cache macro expander objects to avoid thrashing malloc in heavy expansion situations.
This doesn't significantly improve carbon.h, but it does speed up
INPUTS/macro_pounder_obj.c by 48%

Chris Lattner 564f478595 switch function-like macros from using a vector for their arguments to an
explicitly new'd array.  The array never mutates once created, so a vector
is overkill.

Chris Lattner 819f2ef77b switch from using a vector to a smallvector for macro replacement tokens
This speeds up parsing carbon.h by 3.3% by avoiding some malloc traffic for

Chris Lattner 23b7eb677d Finally bite the bullet and make the major change: split the clang namespace
out of the llvm namespace.  This makes the clang namespace be a sibling of
llvm instead of being a child.

The good thing about this is that it makes many things unambiguous.  The
bad things is that many things in the llvm namespace (notably data structures
like smallvector) now require an llvm:: qualifier.  IMO, libsystem and libsupport
should be split out of llvm into their own namespace in the future, which will fix
this issue.

Steve Naroff 98d153c730 Bug #:
Submitted by:
Reviewed by:

Fixed a bug in the parser's handling of attributes on pointer declarators.

For example, the following code was producing a syntax error...

int *__attribute(()) foo;

attrib.c:10:25: error: expected identifier or '('
int *__attribute(()) foo;
                        ^
Changed Parser::ParseTypeQualifierListOpt to not consume the token following
an attribute declaration.

Also added LexerToken::getName() convenience method...useful when tracking
down errors like this.

Chris Lattner 9561a0b3e7 Add support for target-independent builtin functions (like __builtin_abs),
whose decl objects are lazily created the first time they are referenced.
Builtin functions are described by the clang/AST/Builtins.def file, which
makes it easy to add new ones.

This is missing two important pieces:
1. Support for the rest of the gcc builtins.
2. Support for target-specific builtins (e.g. __builtin_ia32_emms).

Just adding this builtins reduces the number of implicit function definitions
by 6, reducing the # diagnostics from 550 to 544 when parsing carbon.h.

I need to add all the i386-specific ones to eliminate several hundred more.
ugh.

Chris Lattner a8654ca2cf Eliminate MultipleIncludeOpt::ReadDirective and all calls to it. Any directives
that are lexed are made up of tokens, so the calls are just ugly and redundant.

the hook though, so we still don't handle #if !defined(X) with the MIOpt.

Chris Lattner d01e291332 Make a fundamental change to the way we represent the location of LexerToken's.
Now, instead of keeping a pointer to the start of the token in memory, we keep the
start of the token as a SourceLocation node.  This means that each LexerToken knows
the full include stack it was created with, and means that the LexerToken isn't
reliant on a "CurLexer" member to be around (lexer tokens would previously go out of
scope when their lexers were deallocated).

This simplifies several things, and forces good cleanup elsewhere.  Now the
Preprocessor is the one that knows how to dump tokens/macros and is the one that
knows how to get the spelling of a token (it has all the context).
