declarators.  This allows the clients (C structs, objc classes, objc 
properties, [future] C++ classes) etc, to do custom processing before invoking
an action.

This has two benefits in the short term:
1) objc ivar processing should be split out of ActOnField into its own ActOn method.
2) the new objc ivar action can take visibility info directly, eliminating 
   AllVisibilities in ParseObjCClassInstanceVariables.
3) objc properties can pass their own special sauce down to sema as well.

(with the goal of eliminating the bitconvert) but I don't know
how to do that safely.  Thoughts welcome.

Teach branch folding pass about implicit_def instructions. Unfortunately we can't just eliminate them since register scavenger expects every register use to be defined. However, we can delete them when there are no intra-block uses.  Carefully removing some implicit def's which enable more blocks to be optimized away.

Bugs are now reported using a combination of "BugType" (previously
BugDescription) and Bug "BugReport" objects, which are fed to BugReporter (which
generates PathDiagnostics). This provides a far more modular way of registering
bug types and plugging in diagnostics.

GRExprEngine now owns its copy of GRCoreEngine, and is not owned by the
ExplodedGraph.

ExplodedGraph is no longer templated on the "checker", but instead on the state
contained in the nodes.

string began at a power of 2 in the string index.  For example, if "ret" started
at position 16, the ret instruction would be assigned code 16, but the mask would be AsmChars[] + Code & 15, not Code & 31.
