regcomp.h: change regexp_internal attribute from I32 to U32
This changes the name_list_idx attribute from I32 to a U32 as it will
never be negative, and as of a963d6d5acabdd8c7 a 0 can be safely used
to represent "no value" for items in the 'data' array.
I noticed this while cleaning up the offsets debug logic and updating
the perlreguts documentation, so I figured I might as well clean it up
at the same time.
