Merge branch 'optim-shift' into tip
* give a correct & sensible warning on negative or over-sized shifts.
* add conservative simplification of such shifts.
* do not optimize the meaningless shift:
* any shift with a negative count
* OP_ASRs with an over-sized shift count.
* try to give a correct negative/too-big error message during simplification.
* simplify chains of shifts.
* simplify ZEXT + ASR into ZEXT + LSR
