Fix GLIBCXX_DEBUG error owing to dereference of end iterator.  There's
no guarantee that an instruction returned by getDependency exists in
the maps.

Add parsing and AST support for GNU "typeof".
Many small changes to lot's of files.
Still some FIXME's, however the basic support is in place.

Redo and generalize previously removed opt for pinsrw: (vextract (v4i32 bc (v4f32 s2v (f32 load ))), 0) -> (i32 load )

Use simple analysis interface to preserve analysis info maintained by other loop passes.

Right now, this interface provides hooks for only to operations, 1) clone basic block 2) delete value.

function attribute for llvm by translation to the InReg parameter attribute 
and fixes test/CFrontend/2002-07-30-SubregSetAssertion.c

front end converts regparm attribute on the gcc function into InReg attribute
