b80ff334d8 Fix an iterator invalidation problem when we decide a phi has a constant value

4a3dc26192 Now that hasConstantValue is more careful w.r.t. returning values that only 
dominate the PHI node, this code can go away.  This also makes passes more
aggressive, e.g. implementing Transforms/CondProp/phisimplify2.ll

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

public header files must be under include/llvm/.

5c1abfecfe Find bugs sooner rather than later. In this case, don't allow the creation 
of instructions that don't have a first-class or void type.

6e6ab3888b As much as I dislike doing this, it's the only fix for VC8.0 that I can come 
up with, even though it's perfectly conformant code.  :(

half.

1404b61b62 In BasicBlock::splitBasicBlock, just use islist::splice to move the instructions, 
instead of a loop that is really inefficient with large basic blocks.

This speeds up the inliner pass on the testcase in PR209 from 13.8s to 2.24s
which still isn't exactly speedy, but is a lot better.  :)
