Chris Lattner 43ba25187b Tweak error recovery for missing semicolon after decl. For this:
void foo() {
  int x
  if (x) {
  }
}

We now emit:

a.c:5:3: error: parse error
  if (x) {
  ^
1 diagnostic generated.

instead of:

a.c:5:3: error: parse error
  if (x) {
  ^
a.c:9:1: error: expected '}'

^
2 diagnostics generated.

Steve Naroff 9717080968 Added Parser::ParseStructDeclaration() as a result of refactoring Parser::ParseStructUnionBody().
Motivation: Objective-C can now share this rule. It also makes Parser::ParseStructUnionBody()
a bit smaller/cleaner..

Next step, refactor Parser::ParseStructUnionBody() so that struct declarations can

Chris Lattner 02c0439a44 Fix a couple of bugs, add some new cool stuff.
1. Fix a todo in Parser::ParseTag, to recover better.  On code like
   that in test/Sema/decl-invalid.c it causes us to return a single
   error instead of multiple.
2. Fix an error in Sema::ParseDeclarator, where it would crash if the
   declarator didn't have an identifier.  Instead, diagnose the problem.
3. Start adding infrastructure to track the range of locations covered
   by a declspec or declarator.  This is mostly implemented for declspec,
   but could be improved, it is missing for declarator.

Thanks to Neil for pointing out this crash.

Steve Naroff fbd098332c Work towards fixing crasher with compound literals...
Before this commit, we crashed in ParseBinOp...

[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang -parse-ast-check compound_literal.c
SemaExpr.cpp:1298: failed assertion `(rhs != 0) && "ParseBinOp(): missing right expression"'

With this commit, we still crash in the newly added action ParseCompoundLiteral (which is progress:-)

[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang -parse-ast-check compound_literal.c

- Fix for C++ casting operators failing during parsing. Deriving the C++ cast
  expressions from CastExpr was the wrong way to go. Its constructor creates
  null QualTypes in one of its constructors. This doesn't work well with how
  the C++ casting expression class wanted to do things. Derive just from Expr
  instead.

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.

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 2e550fea6a When parsing an expr in stmt context, make sure to consume the semicolon
after the expr along with the expr.  If we don't do this, the semicolon
gets parsed as a nullstmt, which makes the generated AST very strange.
