Eliminate catch-all clause from two functions

A stronger version of Dialyzer complained that some case clauses in
functions xaluop_is_shift/1 and xaluop_normalise/1 are unreachable.
These clauses are now commented out.  While at it, I thought that it
would be better to eliminate the catch-all clauses in order to be
certain we properly handle all RTL instructions that are used as
inputs to these functions.

Note: The code will now crash if there are unhandled cases.
