8ee9065162 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

1f970769e8 Prefer non-virtual calls to ConstantInt::isZero over virtual calls to 
Constant::isNullValue() in situations where it is possible.

e5456dea52 Although probably not necessary, guard against a potential assertion by 
using isNullValue() instead of getZExtValue() == 0.

8749d297f5 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.

3d986f6487 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.

9e7640cf02 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.

is 'unsigned'.

ef41400067 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

a117cf4215 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.
