to serve as the entry block.  An empty entry block (just as with an
empty exit block, which we already have) simplifies building analyses on top
of CFGs with very little extra overhead.

Add support for ObjC keyword selectors.

- Add SelectorInfo/SelectorTable classes, modeled after IdentifierInfo/IdentifierTable.
- Add SelectorTable instance to ASTContext, created lazily through ASTContext::getSelectorInfo().
- Add SelectorInfo slot to ObjcMethodDecl.
- Add helper function to derive a SelectorInfo from ObjcKeywordInfo.

Misc: Got the Decl stats stuff up and running again...it was missing support for ObjC AST's.

This patch starts the search at the beginning of the comment string.
After applying this patch, clang -parse-ast-check on negative test
