Implement support for GCC __attribute__.
- Implement "TODO" in Parser::ParseAttributes. Changed the return type from
void to Parser::DeclTy. Changed all call sites to accept the return value.
- Added Action::ParseAttribute and Sema::ParseAttribute to return an
appropriate AST node. Added new node AttributeDecl to Decl.h.
Still to do...hook up to the Decl...

- ParseForStatement(): Put back a test/assignment. My removal of
ParseExprStmt() was a bit over zealous:-(thanks to Chris for pointing it out)
- Add assert to VisitDeclStmt().

Implement some FIXME's that stand in the way of fully typechecking "for"
statements. This involved:
- Adding a DeclStmt AST node (with statement visitor). The DeclStmt
printer is preliminary.
- Added a ParseDeclStmt action, called from Parser::ParseForStatement()
and Parser::ParseStatementOrDeclaration(). DID NOT add to
Parser::ParseIdentifierStatement()...probably could have, however didn't
really understand the context of this rule (will speak with Chris).
- Removed ParseExprStmt (and it's clients)...it was vestigial.

instead of dropping the if and labels (due to break not being in a loop).

actually add it into the declspec for the type being parsed. This allows us
to do correct semantic analysis on:
typedef int bar;
int foo() {
bar a;
return a;
}
This reduces # errors parsing carbon.h from 731 to 654.

#define A {{}}
#define B A A A A A A A A A A

#define E D D D D D D D D D D

#define H G G G G G G G G G G
void foo() {

1. Allow argument list of a call to be empty.
2. Handle expressions in a statement context that start with an identifier.
These are nasty to handle due to the 'label:' production which requires
having two tokens of look-ahead, or by having tricky code (which we
choose to do).
