This is a reroll of [1] which is mostly equivalent to the original RFC but rebased on top of ab/pcre-jit-fixes. The first patch fixes an inconsistency from 685668faaa (grep: stop using a custom JIT stack with PCRE v1, 2019-07-26) where NO_LIBPCRE1_JIT will only affect versions of pcre1 >= 8.32, while support for JIT was added to pcre1 with version 8.20. Technically this is a change of behaviour as originally it was not possible to use JIT with those older versions, but the restriction was somehow arbitrary and caused by the use of JIT fast path. The second patch is mainly refactoring and to make sure the solution from 2fff1e196d (grep: fix NO_LIBPCRE1_JIT to fully disable JIT, 2017-11-12) is working as expected.
