Broke out object copying code into CopyObject from EmitCXXThrowExpr.
Built up another version of CopyObject that can copy from memory for
use in the catch parameter code.
RTTI generation for type matching for catch.
Code to check for the type match for catch.
Code to generate the catch parameter, WIP, need make sure references

Use the more general Evaluate infrastructure for folding constant DeclRefs
...
instead of checking explicitly for an EnumConstantDecl. This folds references

1. Slightly smaller emitted code from emitting a constant instead of a load,
and skipping emitting some constant globals.
2. Some code forgets to define static constant member variables; emitting a
load instead of the value in that case leads to a link error. (Such programs
are technically not well-formed, but in practice build with g++.)

Cleanups and fixes to the nil-receiver checker, some of it fallout the
...
initial transition of the nil-receiver checker to the Checker
interface as done in r89745. Some important changes include:
1) We consolidate the BugType object used for nil receiver bug
reports, and don't include the type of the returned value in the
BugType (which would be wrong if a nil receiver bug was reported more
than once)
2) Added a new (temporary) flag to CheckerContext: DoneEvauating.
This is used by GRExprEngine when evaluating message expressions to
not continue evaluating the message expression if this flag is set.
This flag is currently set by the nil receiver checker. This is an
intermediate solution to allow the nil-receiver checker to properly
work as a plug-in outside of GRExprEngine. Basically, this flag
indicates that the entire message expression has been evaluated, not
just a precondition (which is what the nil-receiver checker does).
This flag *should not* be repurposed for general use, but just to pull
more things out of GRExprEngine that already in there as we devise a
better interface in the Checker class.
3) Cleaned up the logic in the nil-receiver checker, making the
control-flow a lot easier to read.

- Outside the "if", to ensure that we destroy the condition variable

else-local cleanups at the end of the corresponding block when the

Clean up the Checker API a little more, resolving some hidden bugs
...
along the way. Important changes:
1) To generate a sink node, use GenerateSink(); GenerateNode() is for
generating regular transitions. This makes the API clearer and also
allows us to use the 'bool' option to GenerateNode() for a different
purpose.
2) GenerateNode() now automatically adds the generated node to the
destination ExplodedNodeSet (autotransition) unless the client
specifies otherwise with a bool flag. Several checkers did not call
'addTransition()' after calling 'GenerateNode()', causing the
simulation path to be prematurely culled when a non-fail stop bug was
encountered.
3) Add variants of GenerateNode()/GenerateSink() that take neither a
Stmt* or a GRState*; most callers of GenerateNode() just pass in the
same Stmt* as provided when the CheckerContext object is created; we
can just use that the majority of the time. This cleanup also allows
us to potentially coelesce the APIs for evaluating branches and
end-of-paths (which currently directly use builders).
4) addTransition() no longer needs to be called except for a few
cases. We now have a variant of addTransition() that takes a
GRState*; this allows one to propagate the updated state without
caring about generating a new node explicitly. This nicely cleaned up
a bunch of cases that called autoTransition() with a bunch of
