(Stmt*,LocationContext*) pairs to SVals instead of Stmt* to SVals.

This is needed to support basic IPA via inlining.  Without this, we cannot tell
if a Stmt* binding is part of the current analysis scope (StackFrameContext) or
part of a parent context.

This change introduces an uglification of the use of getSVal(), and thus takes
two steps forward and one step back.  There are also potential performance implications
of enlarging the Environment.  Both can be addressed going forward by refactoring the
APIs and optimizing the internal representation of Environment.  This patch
mainly introduces the functionality upon when we want to build upon (and clean up).

chain to determine whether any declaration of the given entity is
visible, eliminating the redundant (and less efficient)
getPreviousDeclaration() implementation.

This tweak uncovered an omission in the handling of
RedeclarableTemplateDecl, where we weren't making sure to search for
additional redeclarations of a template in other module files. Things
would be cleaner if RedeclarableTemplateDecl actually used Redeclarable.

__gxx_personality_v0 update.  This is completely untested code.  But my brain is scrambled and I wanted to get it checked in.  Code review from anyone who knows anything at all about personality functions would be much appreciated.  What is in here is borrowed heavily from llvm/examples/ExceptionDemo/ExceptionDemo.cpp.  There are some calls to abort() that should probably be changed to return an error code instead.  There may be encodings under readEncodedPointer that need to be implemented.  And my handling of type_info is almost a complete guess.

parser was creating malformed resuls.  When the
location of a variable is computed by reading a
register and adding an offset, we shouldn't say
that the variable's value is located in that
register.  This was confusing the expression
parser when trying to read a variable captured
by a block.

include stack to find the first file that is known to be part of the
module. This copes with situations where the module map doesn't
completely specify all of the headers that are involved in the module,
which can come up when there are very strange #include_next chains
(e.g., with weird compiler/stdlib headers like stdarg.h or float.h).
