make sure to add 'temp' to the stmt tree as a declstmt.

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.

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.

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...

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.

actually add it into the declspec for the type being parsed. This allows us
to do correct semantic analysis on:

int foo() {

return a;

This reduces # errors parsing carbon.h from 731 to 654.

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).
