number of common tail instructions more efficiently

Fix <rdar://problem/5924225> clang ObjC rewriter: objc_exception_throw declaration in preamble does not match objc/objc-exception.h.

DO NOT pre-defined __OBJC2__. The __OBJC2__ macro should only be defined when targeting the new, Apple 2.0 *runtime ABI*. It is not intended to be used to #ifdef ObjC 2.0 langauge features. This is unfortunate (given it's name). In a perfect world, this defined would be named __OBJC2_RUNTIME_ABI__. Oh well.

Fixed the build breakage, sorry for that.

vector of the same element type and half the width, with the high, low, even,
and odd elements respectively.

Allow member references to member references, so that .hi.hi gives you the high
quarter of a vector.  This is fairly convenient syntax for some insert/extract
operations.

Remove some unnecessary methods/types in the ExtVectorElementExpr class.
