First clean up the strange API of tryConstantFoldOp where it took an
immediate operand value, but no indication of which operand it was the
value for.

Second clean up the loop that calls tryConstantFoldOp so that it does
not have to restart from the beginning every time it folds an
instruction.

This is NFCI but there are some minor changes caused by the order in
which things are folded.
