their associated APIs.  We no longer need separate SymbolData objects
for fields, variables, etc.  Instead, we now associated symbols with
the "rvalue" of a MemRegion (i.e., the value stored at that region).
Now we only have two kinds of SymbolData objects: SymbolRegionRValue
and SymbolConjured.

This cleanup also makes the distinction between a SymbolicRegion and a
symbolic value that is a location much clearer.  A SymbolicRegion
represents a chunk of symbolic memory, while a symbolic location is
just a "pointer" with different possible values.  Without any specific
knowledge, a symbolic location resolves (i.e., via a dereference) to a
SymbolicRegion.  In the future, when we do better alias reasoning, a
symbolic location can become an alias for another location, thus
merging the constraints on the referred SymbolicRegion with the other
region.

Uncomment the define in Ownership.h to disable the smart pointers.
Disabled, the smart pointers no longer contain a pointer
to the action, and no longer have special destruction or
copying semantics. They are, compiler willing, raw
pointers or ActionResult equivalents.

Eliminate a couple of fields from TargetRegisterClass: SubRegClasses and SuperRegClasses. These are not necessary. Also eliminate getSubRegisterRegClass and getSuperRegisterRegClass. These are slow and their results can change if register file names change. Just use TargetLowering::getRegClassFor() to get the right TargetRegisterClass instead.

designated initializers. This implementation should cover all of the
constraints in C99 6.7.8, including long, complex designations and
computing the size of incomplete array types initialized with a
designated initializer. Please see the new test-case and holler if you
find cases where this doesn't work.

There are still some wrinkles with GNU's anonymous structs and
anonymous unions (it isn't clear how these should work; we'll just
follow GCC's lead) and with designated initializers for the members of a
union. I'll tackle those very soon.

CodeGen is still nonexistent, and there's some leftover code in the
parser's representation of designators that I'll also need to clean up.

Static Analyzer: Replace LiveSymbols/DeadSymbols sets with a new object called "SymbolReaper".  Right now it just consolidates the two and cleans up some client code, but shortly it will be used to enable "lazy computation" of live symbols for use with RegionStore.
