 - RegionView and RegionViewMap is introduced to assist back-mapping from
   super region to subregions.
 - GDM is used to carry RegionView information.
 - AnonTypedRegion is added to represent a typed region introduced by pointer
   casting. Later AnonTypedRegion can be used in other similar cases, e.g.,
   malloc()'ed region.
 - The specific conversion is delegated to store manager.

Add a test case for compound assignments that lazily symbolicate the value of the LHS when the computation type is an integer of more bits.

Reverted part of r59335: http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20081110/009243.html
In that patch I added a bogus type promotion for unary '!'.

The real bug was more fallout from edges cases with compound assignments and conjured symbolic values.  Now the conjured value has the type of the LHS expression, and we do a promotion to the computation type.  We also now correctly do a conversion from the computation type back to the LHS type.

Implement FIXME in GRExprEngine::VisitUnaryOperator() to handle implicit conversions caused by the '!' operator.  This required adding some logic to GRSimpleVals to reason about nonloc::LocAsInteger SVals.  This code appears to work fine, but it should eventually be cleaned up.

SynthBlockInitExpr() was not adding by-ref arguments to the init expr.

- Block-expression for 'ObjCForCollectionStmt' is not alive before it occurs
- Recursively visit 'element' expression for ObjCForCollectionStmt to get liveness for referenced block-level expressions and variables.

Second attempt at implementation transfer function support for ObjCForCollectionStmt.  We now assume that the 'element' expression can be any lvalue.

llvm-svn: 59313

Flow-sensitive uninitialized values analysis: properly handle the 'element' expression of ObjCForCollectionStmt (can be anything).

function call created in response to the use of operator syntax that
resolves to an overloaded operator in C++, e.g., "str1 +
str2" that resolves to std::operator+(str1, str2)". We now build a
CXXOperatorCallExpr in C++ when we pick an overloaded operator. (But
only for binary operators, where we actually implement overloading)

I decided *not* to refactor the current CallExpr to make it abstract
(with FunctionCallExpr and CXXOperatorCallExpr as derived
classes). Doing so would allow us to make CXXOperatorCallExpr a little
bit smaller, at the cost of making the argument and callee accessors
virtual. We won't know if this is going to be a win until we can parse
lots of C++ code to determine how much memory we'll save by making
this change vs. the performance penalty due to the extra virtual
calls.

Don't require us to manually number the statements and expressions in StmtNodes.def. We don't need stable numbers yet, renumbering is a pain, and LAST_STMT had the wrong value anyway.

Rename ExprDeclBitVector to BlkExprDeclBitVector, and store mappings from Stmt* to bit indices instead using Expr*.
