For checking if a symbol >= value, we need to check if symbol == value || symbol
> value. When checking symbol > value and we know that symbol != value, the path
is infeasible only if value == maximum integer.
For checking if a symbol <= value, we need to check if symbol == value || symbol
< value. When checking symbol < value and we know that symbol != value, the path
is infeasible only if value == minimum integer.
Updated test case exercising this logic: we only prune paths if the values are
unsigned.

Added AnalysisConsumer, a meta-level ASTConsumer class to drive various
...
analyses. This potentially is the primordial origins of a Clang-equivalent
"PassManager".
The new AnalysisConsumer interface allows multiple analyses to be run from a
single invocation of Clang.
Migrated the logic of "-warn-dead-stores" and "-warn-uninit-values" to use the
new AnalysisConsumer interface. The new interface results in a significant code
reduction to incorporate an analysis into the Driver.
Updated a test case to (correctly) acknowledge that it contains a dead store
(this check wasn't being performed because it was previously masked by
-warn-uninit-values).

1) Check if a dead store appears as a subexpression. For such cases, we emit

2) Don't emit a dead store warning when assigning a null value to a pointer.
This is a common form of defensive programming. We may wish to make
this an option to the the checker one day.

Added uninitialized-values (path-sensitive) test case as a regression test
...
for the fix in r50178 (http://llvm.org/viewvc/llvm-project?rev=50178&view=rev ).
This fix was for <rdar://problem/5881148>.

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

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.

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.

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.

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.

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.
