- Added support for ObjCForCollectionStmt
- Fixed bug where expression values would be always set to uninitialized when loops were involved

Introduce a single AST node SizeOfAlignOfExpr for all sizeof and alignof expressions, both of values and types.

Need to modify GRExprEngine, LiveVariables, and UninitializedValues to understand this construct.

 - Emits an unconditional branch, with extra logic to avoid generating
   spurious branches out of dummy blocks.

the size of the -O0 output on some cases.  For example, on expr.c from
176.gcc, it shrinks the .ll file from 43164 to 42835 lines, and removed
references to two external symbols.

condition is a constant.  This shrinks -O0 codegen by quite a bit
on some cases.

"dummy" blocks (blocks just used to make sure we have a place to dump
code to).

Some cleanups to the declaration/checking of overloaded operators in C++. Thanks to Sebastian for the review

Implement RegionStoreManager::RemoveDeadBindings(). This prunes several false warning caused by removal of symbolic constraints. Currently we just mark all symbols live. Further optimization for dead binding removal needed.

speeds up the compiler by ~8% at -emit-llvm -O0.

1. emit proper debug info for forward decls of structs.
2. emit DW_TAG_member nodes around members of a field like llvm-gcc does.

This slows down debug info generation, but is required for correctness.
