lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.

represent symbolic memory.

Right now only some ctors are switched over.  I need to switch them all
over so I can change the dtor over.

This lets us experiment with region allocation and other things in the 
future.

Patched various ASTConsumers (such as ASTDumper) to have more support for
processing ObjCMethodDecl. CFGVisitor now builds CFGs for ObjCMethodDecls.

An address space name cannot be used to qualify an object that has automatic
storage duration.  Still not catching ASQual'd allocas of array type, just 
scalars at the moment.

we gracefully back out and return NULL for the CFG, allowing clients to skip
analyzing functions with these CFGs. We will add support later.

Modified base ASTConsumer "CFGVisitor" to detect when a CFG is not constructed
and to emit a warning.

- For explicit ivar refers, make sure the cast is propagated to the AST.
- Don't free the base (since it is still in use).
This fixes the recent regression to test/Rewriter/objc-ivar-receiver-1.m.

Changed CallRetValSymbol to SymbolConjured to allow "conjured" symbols to be created for any expression, not just CallExprs.
Added experimental support for conjuring symbols during assingments where the RHS is "unknown".  This allows more value tracking for path-sensitivity.
Fixed bug in "assumption" logic when processing symbolic constraints; we would improperly mark constraints we didn't support as infeasible.

Avoid using the "unnamed struct field" extension (enabled with -fms-extensions). This feature/extension silently does the wrong thing in g++. As far as I can tell, g++ simply throws the field away entirely (note that it works fine with gcc). Since I am now always casting the object (for other reasons), accessing protected/public fields simply requires the cast refer to the defining class. This solution is simpler all around (thanks to Chris for suggesting it).
