library/lexer.m:
Merge the 'integer' and 'big_integer' tokens and extend them to include
signedness and size information. This conforms to recent changes to
the rest of the system and is another step towards supporting additional
types of integer literal.
library/parser.m:
mdbcomp/trace_counts.m:
Conform to the above change.
