GRExprEngine (VisitCast):
- When using StoreManager::CastRegion, always use the state and value it returns to generate the next node.  Failure to do so means that region values returned that don't require the state to be modified will get ignored.

MemRegion:
- Tighten the interface for ElementRegion.  Now ElementRegion can only be created with a super region that is a 'TypedRegion' instead of any MemRegion.  Code in BasicStoreManager/RegionStoreManager already assumed this, but it would result in a dynamic assertion check (and crash) rather than just having the compiler forbid the construction of such regions.
- Added ElementRegion::getArrayRegion() to return the 'typed version' of an ElementRegion's super region.
- Removed bogus assertion in ElementRegion::getType() that assumed that the super region was an AnonTypedRegion.  All that matters is that it is a TypedRegion, which is now true all the time by design.

BasicStore:
- Modified getLValueElement() to check if the 'array' region is a TypedRegion before creating an ElementRegion.  This conforms to the updated interface for ElementRegion.

RegionStore:
- In ArrayToPointer() gracefully handle things we don't reason about, and only create an ElementRegion if the array region is indeed a TypedRegion.

PTH: Added minor 'sibling jumping' optimization for iterating over the side table used for fast preprocessor block skipping.  This has a minor performance improvement when preprocessing Cocoa.h, but can have some wins in pathologic cases.

Added PTH optimization to not process entire blocks of tokens that appear in skipped preprocessor blocks.  This improves PTH speed by 6%.  The code for this optimization itself is not very optimized, and will get cleaned up.

Substantially improve error recovery after broken if conditions by
parsing the full if when we have a semantic error instead of using
parser recovery techniques to recover from a semantic error.

the type of the enumeration once the enumeration has been defined.

Fix the overloading test-case to properly create enums that promote
the way we want them to.

Implement C++0x promotions from enumeration types to long
long/unsigned long long. We're using these promotions in Carbon.h
(since long long is a common extension).
