Ted Kremenek eccf3e5821 Added "nonlval::LValAsInteger" to represent abstract LVals casted to integers, allowing us to track lvals when they are casted back to pointers.

Ted Kremenek 4a78c3ae11 Refactored all logic to run the GRSimpleVals and CFRef checker into a common
code path in the clang driver.

Renamed options --grsimple to -checker-simple and -check-cfref to -checker-cfref.

Ted Kremenek f646774f32 Added path-sensitive check for return statements that return the address
of a stack variable.  This is the path-sensitive version of a check that
is already done during semantic analysis.

Ted Kremenek fb475ec504 Changed merge operation for uninitialized values analysis to "intersect" (previous union).
The effect is that if a variable is uninitialized along a branch (but initialized along another), at merge points it is considered uninitialized.  Previously we had the opposite behavior.  The new behavior is more conservative, and more in line with gcc's behavior.

Anders Carlsson 801c5c7467 GCC has an extension where the left hand side of the ? : operator can be omitted. Handle this in a few more places.

Bill Wendling 8da1db4f34 The checking for the delimiters of expected error/warning messages was
looking only for { and } instead of {{ and }}. Changed it to check for
this explicitly.

Ted Kremenek 0d20033c6a Added more test cases for uninitialized values checker.

Ted Kremenek 2e04d73d83 Fixed bogus culling of uninitialized-values "taint" propagation during assignments.
We accidentally were throttling the propagation of uninitialized state across
assignments (e.g. x = y).  Thanks to Anders Carlsson for spotting this problem.

Added test cases to test suite to provide regression testing for the
uninitialized values analysis.
