mechanism can be implemented simply by affixing the Observer to an
analysis meta data, so it doesn't need to be a required type. This
also permits analyses not to implement an Observer if it doesn't make
sense.
Changed "DataflowValues::MetaDataTy" to
"DataflowValues::AnalysisDataTy" to reflect that the type
enscapsulated the data associated with analyzing a given CFG.
Changed CFGStmtVisitor::BlockStmt_VisitImplicitControlFlowStmt(Stmt*)
to ...VisitImplicitControlFlowExpr(Expr*). The type narrowing is more
precise and more useful to clients.
Added CFGStmtVisitor::BlockStmt_VisitExpr to reflect the visitation of
expressions at the block statement level. This captures all implicit
control-flow statements as well as other expressions that are hoisted
to the block level (such as conditions for terminators and function
calls). This is especially useful for dataflow analysis.

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 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.

"The ExpectedStr search was starting at the end of the comment string.
This patch starts the search at the beginning of the comment string.
After applying this patch, clang -parse-ast-check on negative test
case source files worked as expected."

- Allow classnames as the receiver (removing a FIXME from ParseObjCMessageExpression).
- Added a FIXME to ParseObjCMessageExpression()...we need to return a message expr AST node!

The previous naming scheme was confusing, since it resulted in both the Parser and Action modules having methods with the same name. In addition, the Action module never does any parsing...
