GRExprEngine:
  Use PostStore in EvalStore.
  Use a second version of EvalStore in EvalBinaryOperator to associate the store with the expression on the LHS.

Bug fix: for the base transfer function logic for casts, handle const casts as just propagating the value.

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.

arbitrary expr, not just a assign expr.  The grammar comment
was right, the code was just wrong.

'symbol operator-reverse int'. This patch is a combination of code from
Zhongxing Xu and myself (Zhongxing noticed this bug for the cases of
relational operators).

Change implementation of NSError** coding-style check to be invoked at the end of the retain/release analysis.

Also added a couple simple tests from the "gcc.apple" test suite.

Also tweaked the create function to take an explicit output file.

"Method accepting NSError** argument should have non-void return value to indicate that an error occurred."

Test case written, but the header needs to be delta-debugged reduced.  Will commit shortly.

 - Enables use of ABIArgInfo::Expand when needed. This greatly
   improves our x86 ABI compatibility.

 - As the infrastructure for target specific ABI handling isn't built
   yet, this change means ABI compatibility on other platforms is once
   again broken in a different way than before.

 - Upcoming: Figure out how to refactor ABI handling into
   targets. More documentation.

Ensure that ABIArgInfo::Default implementation for aggregrate types
is sensible (StructRet on return and ByVal on arguments).
