Minor code beautification in regexp.c.

Remove duplicated code (apparently introduced by commitc8ea87e).Also get rid of some PG_USED_FOR_ASSERTS_ONLY variables we don'treally need to have.Li Japin, Tom LaneDiscussion:https://postgr.es/m/PS1PR0601MB3770A5595B6E5E3FD6F35724B6360@PS1PR0601MB3770.apcprd06.prod.outlook.com
