Reid Spencer 557ab15e71 Apply the VISIBILITY_HIDDEN field to the remaining anonymous classes in 
the Transforms library. This reduces debug library size by 132 KB, debug
binary size by 376 KB, and reduces link time for llvm tools slightly.

Reid Spencer cddc9dfe97 Implement review feedback for the ConstantBool->ConstantInt merge. Chris 
recommended that getBoolValue be replaced with getZExtValue and that
get(bool) be replaced by get(const Type*, uint64_t). This implements
those changes.

Chris Lattner 79a42ac941 Switch over Transforms/Scalar to use the STATISTIC macro. For each statistic 
converted, we lose a static initializer.  This also allows GCC to emit warnings
about unused statistics.

Chris Lattner 700b873130 Detemplatize the Statistic class. The only type it is instantiated with 
is 'unsigned'.

Chris Lattner 6441cf93c9 Handle single-entry PHI nodes correctly. This fixes PR877 and

Nate Begeman b392321cae Fix a fixme in CondPropagate.cpp by moving a PhiNode optimization into 
BasicBlock's removePredecessor routine.  This requires shuffling around
the definition and implementation of hasContantValue from Utils.h,cpp into
Instructions.h,cpp

Chris Lattner 16a50fd0a0 a new simple pass, which will be extended to be more useful in the future. 
This pass forward branches through conditions when it can show that the
conditions is either always true or false for a predecessor.  This currently
only handles the most simple cases of this, but is successful at threading
across 2489 branches and 65 switch instructions in 176.gcc, which isn't bad.
