Arthur Eubanks	9660563950	[llvm-reduce] Add reduction passes to reduce operands to undef/1/0 ... Having non-undef constants in a final llvm-reduce output is nicer than having undefs. This splits the existing reduce-operands pass into three, one which does the same as the current pass of reducing to undef, and two more to reduce to the constant 1 and the constant 0. Do not reduce to undef if the operand is a ConstantData, and do not reduce 0s to 1s. Reducing GEP operands very frequently causes invalid IR (since types may not match up if we index differently into a struct), so don't touch GEPs.
