Ted Kremenek aadd463e0e Enhance SimpleSValuator to handle nonloc::LocAsInteger -> location casts.

Ted Kremenek c7b1dade86 Move RegionStoreManager over to using new 
ValueManager::makeArrayIndex()/convertArrayIndex() methods.  This
handles yet another crash case when reasoning about array indices of
different bitwidth and signedness.

Ted Kremenek b63f71528e Enhance SimpleSValuator::EvalBinOpNN to recognize the trivial case 
where we are comparing a symbolic value against itself, regardless of
the nature of that symbolic value.

This enhancement identified a case where RegionStoreManager is not
correctly symbolicating the values of the pointees of parameters.  The
failing test is now in 'test/Analysis/misc-ps-region-store.m', with
that test file now (temporarily) marked XFAIL.
