Chris Lattner 196c166a06 Enhance heap sra to be substantially more aggressive w.r.t PHI
nodes.  This allows it to do fairly general phi insertion if a 
load from a pointer global wants to be SRAd but the load is used
by (recursive) phi nodes.  This fixes a pessimization on ppc
introduced by Load PRE.
