Jordy Rose df28e8ec41 - Allow making ElementRegions with complex offsets (expressions or symbols) for the purpose of bounds-checking.
- Rewrite GRState::AssumeInBound to actually do that checking, and to use the normal constraint path.
- Remove ConstraintManager::AssumeInBound.
- Teach RegionStore and FlatStore to ignore those regions for now.

Zhongxing Xu ee770d40fd StoreManager::RemoveDeadBindings() can take a Store instead of an entire GRState now.

Jordy Rose ac0ab20e3b Add a callback for when region changes occur. Still somewhat of a work-in-progress, but working! Effect on clients: all changes to a store now go through GRState.

Zhongxing Xu 8de0a3d8c3 MemRegion can refer to ASTContext without external help.

Jordy Rose c88c74cb2f Remove InvalidateRegion from stores, since it's no longer called from outside.

Zhongxing Xu 42b8c30de6 Allow offsets to be negative. Out-of-bound cases are checked elsewhere. We
shouldn't put restrictions in store manager.

Zhongxing Xu fd91d27630 Improve flat store: MemRegion::getAsOffset() computes a region's offset within
the top-level object. FlatStore now can bind and retrieve element and field
regions.
PR7297 is fixed by flat store.

Ted Kremenek bd862711fd Fix PR 7475 by enhancing the static analyzer to also invalidate bindings for non-static global variables
when calling a function/method whose impact on global variables we cannot accurately estimate.
This change introduces two new MemSpaceRegions that divide up the memory space of globals, and causes
RegionStore and BasicStore to consult a binding to the NonStaticGlobalsMemSpaceRegion when lazily
determining the value of a global.

Jordy Rose f7488ec6dc Add an ivar to SymbolReaper for the current statement, and then stop passing the current statement around everywhere. Preparation for symbolic extents.

Zhongxing Xu d4f1294f1e Remove extents of dead symbolic regions when RemoveDeadBindings.
This requires creating new persistent states due to the nature of GDM.

Zhongxing Xu 03fd76663e Mark CXXThisRegion in the current or parent stack frame context as live so that
their bindings are not removed.

Zhongxing Xu 6d3cc382df Since now we store the cast type with an ElementRegion, there is
no need to store a type with SymbolRegionValue.

Zhongxing Xu b02d4a0d11 Unify the implementation of getLValueElement of store managers.
It's more sophisticated than the original one of BasicStore. But it does
matter.
