Pawel Bylica f1975e4c5f Merge r232176: ConstantFold: Fix big shift constant folding ...

Constant folding for shift IR instructions ignores all bits above 32 of
second argument (shift amount).
Because of that, some undef results are not recognized and APInt can
raise an assert failure if second argument has more than 64 bits.
