6833ffe8b8 For PR950: 
Make necessary changes to support DIV -> [SUF]Div. This changes llvm to
have three division instructions: signed, unsigned, floating point. The
bytecode and assembler are bacwards compatible, however.

1abe8bd233 During vector shuffle lowering, we sometimes commute a vector shuffle to try 
to match MOVL (movss, movsd, etc.). Don't forget to commute it back and try
unpck* and shufp* if that doesn't pan out.

b9780660dd Fix for PR960. Improves bugpoint so that it removes global variable 
initializers as well. This is only a first pass. It can be slow because
it clones the module for each pass. An obvious improvement is not to do that.

cb480ce29c TargetData is not subclassed. So no need to have virtual method.

4b204306fa Targets should depend on all the intrinsics.td files also, otherwise they 
will compute a locally wrong numbering for the intrinsics.  This fixes a
nasty issue where the x86 backend started miscompiling stuff in a 'cvs up'd
build after the altivec intrinsics were added.

in which case the LHS is treated as a bool.
