This fixes bug: FuncResolve/2002-08-19-ResolveGlobalVarsEasier.ll
And bug: SingleSource/UnitTests/2002-10-09-ArrayResolution.c
Note that this does not fix bug:
FunctionResolve/2002-08-19-ResolveGlobalVars.ll because replaceAllUsesWith
breaks when a constantexpr is pointing to the thing being replaced. This
is more of an infrastructure problem than anything.

don't have time to fix the regression now, so I must disable the

makes other transformations much more powerful as well!

New functionality for instcombine:
...
* New ReplaceInstUsesWith function to factor out tons of common code
This needs to be used more in the future still, but it's a good start
* New InsertNewInstBefore to allow multi-instruction replacements
* Change getMaxValue functions to isAllOnesValue function, which doesn't
have to CREATE/lookup a new constant. Also the name is accurate
* Add new isMaxValue, isMinValue, isMaxValueMinusOne, isMinValuePlusOne
functions: This should be moved to Constant* classes eventually
* Implement xor X, ALLONES -> not X
* Fold ALL setcc's of booleans away
* Handle various SetCC's for integers against values at the end of their
ranges, possibly off by one. This implements the setcc-strength-reduce.ll
testcase.
