[globalisel][tablegen] Fix the misuse of STATISTICS() on release builds (like r307088) after r307133.

r307133 brought back a couple instances of the same mistake that was already
fixed by r307088. Fixed it again.

Using NumPatternEmitted as a unique id for the tables is not valid on release
builds since the counters don't count in that case.
