CallExprs as those edges help cause a n^2 explosion in the number of
destructor calls.  Other consumers, such as static analysis, that
would like to have more a more complete CFG can select the inclusion
of those edges as CFG build time.

This also fixes up the two compilation users of CFGs to be tolerant of
having or not having those edges.  All catch code is assumed be to
live if we didn't generate the exceptional edges for CallExprs.

Don't suggest the developer use 'arc4random' instead of 'rand' when that function is not available.  Fixes PR 6012.

"ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits
ones as appropriate. 

Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType, 
fromQuantity(), and getQuantity() for clarity.

This with previous patch fixes a OSAtomic test case.

value bindings.  Along with a small change to OSAtomicChecker, this
resolves <rdar://problem/7527292> and resolves some long-standing
issues with how values can be bound to the same physical address by
not have the same "key".  This change is only a beginning; logically
RegionStore needs to better handle loads from addresses where the
stored value is larger/smaller/different type than the loaded value.
We handle these cases in an approximate fashion now (via
CastRetrievedVal and help in SimpleSValuator), but it could be made
much smarter.

(1) Introduce a new 'BindingKey' class to match 'BindingValue'.  This
gives us the flexibility to change the current key value from 'const
MemRegion*' to something more interesting.

(2) Rework additions/removals/lookups from the store to use new
'Remove', 'Add', 'Lookup' utility methods.

No "real" functionality change; just prep work and abstraction.

CallExpr/ObjCMessageExpr can be visited in an "lvalue" context if it
returns a struct temporary.  Currently the analyzer doesn't reason
about struct temporary returned by function calls, but we shouldn't
crash here either.

cases were ruled out (and the analysis state for the default case
would be infeasible) we would still consider the default case
possible.  This fixes PR 5969.

Make static analysis support for C++ 'this' expression context-sensitive.  Essentially treat 'this' as a implicit parameter to the method call, and associate a region with it.

GRStateManager.  Having these references was an abstraction violation,
as they really should only be known about GRExprEngine.

This change required adding a new 'ProcessAssume' callback in
GRSubEngine.  GRExprEngine implements this callback by calling
'EvalAssume' on all registered Checker objects as well as the
registered GRTransferFunc object.

Add new states for symbolic regions tracked by malloc checker. This enables us
to do malloc checking more accurately. See test case.
