509ee95023 IntegerMatcher: Fix data type of loop counters 
ClassTemplate->ProtoLengths[n] is of type uint8_t, so use that for
the related loop counters, too.

afc099b9f4 intmatcher: Split data_table 
The old code was a hack to improve the performance.

The new code is clearer and results in the same binary when compiling
with gcc 8.3.0, so it looks like the old hack is no longer needed with
modern compilers.
