shift: avoid simplification of ASR(LSR(x,0),N)
In most circumstances, the case where the LSR's count is zero
won't happen because it would have been optimized away before.
However there is a very small posibility it would happen:
at the first run of the simplification loop,
if the LSR and the ASR are in two different Basic Blocks and
the ASR's BB is processed before the LSR's BB (rare)
