Several small patches to do pretty printing for objective-c top-level decls
(minimal printing), Derive ObjcClassDecl from Decl. Ted may want to
take note of the change I made to CFGRecStmtDeclVisitor.h
Removed unnecessary base class from some of objective-c classes:
ObjcProtocolDecl is now derived from ScopedDecl. ObjcForwardProtocolDecl from Decl.
ObjcImplementationDecl fom NamedDecl.

improve layering:
Now instead of IdentifierInfo knowing anything about MacroInfo,
only the preprocessor knows. This makes MacroInfo truly private
to the Lex library (and its direct clients) instead of being
accessed in the Basic library.

Remove the PPID bitfield from IdentifierInfo, shrinking it by a word
(because all bitfields now fit in 32 bits). This shrinks the identifier
table for carbon.h from 1634428 to 1451424 bytes (12%) and has no impact
on compile time.

First step to fixing a long lived layering violation: this
moves the MacroInfo pointer to a side hash table (which currently
lives in IdentifierTable.cpp). This removes a pointer from
Identifier info, but doesn't shrink it, as it requires a new bit
be added. This strange approach with the 'hasmacro' bit is needed
to not lose preprocessor performance.

simplify the interfaces to create selectors: getSelector can take any
number of arguments now and does the right thing, but the nullary/unary
accessors are preserved as convenience functions. This allows us to
slightly simplify clients.

introduce a new NamedDecl class, switch a couple of things over to using it.
NamedDecl is a Decl that has an IdentifierInfo (for example, ScopedDecl),
but not ObjcMethodDecl.
Simplify some code in ActOnAddMethodsToObjcDecl, by doing the cast from
DeclTy to Decl at the start of the method.

Implement DenseMapInfo for Selector, allowing use of DenseMap/DenseSet of
Selector's instead of requiring void* to be used. I converted one use of
DenseSet<void*> over to use DenseSet<Selector> but the others should change
as well.

Layering refinements for selectors (suggested by Chris). Specifics...
- Add SelectorTable, which enables us to remove MultiKeywordSelector from the public header.
- Remove FoldingSet from IdentifierInfo.h and Preprocessor.h.
- Remove Parser::ObjcGetUnarySelector and Parser::ObjcGetKeywordSelector, they are subsumed by SelectorTable.
- Add MultiKeywordSelector to IdentifierInfo.cpp.
- Move a bunch of selector related methods from ParseObjC.cpp to IdentifierInfo.cpp.
- Added some comments.

Finish renaming ObjC declaration actions.
Add comments.
Switch to new indentation style for the Action class. Since many actions take many arguments, the new style will...
- make it easier to add/remove arguments without messing up the indentation...
- make it easier to add comments to each argument (see ActOnMethodDeclaration for an example)...
- in general, just makes it easier to see what is being passed.
The rest of Actions will be converted "lazily"...there is no immediate need to hack all the existing methods.

Rename several ObjC action methods to use the "ActOn" prefix (still a few more to do).
Remove Action::ObjCStartCategoryInterface/ObjCFinishInterface - they are unused.

Rename ObjcProtocolDecl::getIsForwardProtoDecl() to isForwardDecl().

Two reasons:
#1: boolean predicates should start with "is".
#2: Since these two sets of methods represent the same concept, they should be named the same (polymorphism is good:-)
Previously, I warned those methods not implemented in implementation class/category.
Now, I also warn those class/categories which are incomplete because of this.

Add comment to ObjcClassDecl.
Move ObjcClassDecl to be next to ObjcForwardProtocolDecl. Since they are very similar, might want to unify their names (e.g. ObjcForwardClassDecl).
Change indentation of ObjcForwardProtocolDecl to conform to everything else in DeclObjC.h.

CFG objects now internally store a (lazily created) map from block-level
expressions to IDs. This is used by various dataflow analyses, but is
also useful for anyone querying a CFG to determine where an expression
is evaluated.
Moved two bitfields back to top of class ObjcMethodDecl so they pack
with those in their base class. In response to clattner's

Removed "hasImplicitControlFlow" from class CFG, and moved it to class Stmt
as a member function. This function is no longer needed within the CFG
class, and logically belongs to the Stmt class as a predicate for a
Stmt instance.

Add a new getLength() method to IdentifierInfo, which relies on a newly added
method to StringMapEntry. Steve, please use this to remove the
strlen calls in selector processing.
Patch to remove use of has table for protocol name lookup. This patch mirrors my
previous patch to do the same for class name lookup using a hash table.
Removed use of hash table for class decls and do a name look up directly.
There is still an issue if doing ScopedLookup is an overkill and we can
just access the decl using the identifier.
Added ProgramEdge.h, which defines ProgramEdge (and subclasses) that
encapsulate a program point within a CFG for use by our path-sensitive
dataflow solver.

Yesterday I discovered that 78% of all selectors in "Cocoa.h" take 0/1 argument.
This motivated implementing a devious clattner inspired solution:-)
This approach uses a small value "Selector" class to point to an IdentifierInfo for the 0/1 case. For multi-keyword selectors, we instantiate a MultiKeywordSelector object (previously known as SelectorInfo). Now, the incremental cost for selectors is only 24,800 for Cocoa.h! This saves 156,592 bytes, or 86%!! The size reduction is also the result of getting rid of the AST slot, which was not strictly necessary (we will associate a selector with it's method using another table...most likely in Sema).
This change was critical to make now, before we have too many clients.
I still need to add some comments to the Selector class...will likely add later today/tomorrow.
