Use less memory in compiling regexes
This is at least a partial patch for [perl #127392], cutting the maximum
memory used on my box from around 8600kB to 7800kB. For [perl #127568],
which has been merged into #127392, the savings are even larger, about
37%
Previously a large number of large mortal SVs could be created while
compiling a single regex pattern, and their accumulated memory quickly
added up. This changes things to not use so many mortals.

regcomp.c: Guard against corrupting inversion list SV
I don't know of any cases where this happens, but in working on the next
commit I triggered a problem with shrinking an inversion list so much
that the required 0 UV at the beginning was freed.

XXX partial don't push regex: Add ASCII/NASCII regnodes
These are a little more efficient than using the POSIXA(:ascii:)
mechanism.
