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.
