[JSC][Yarr] Clean up FixedCount parentheses
https://bugs.webkit.org/show_bug.cgi?id=306951
rdar://169611825
Reviewed by Yijia Huang.
We found a bit wrong matchAmount decrement code in Yarr JIT with
FixedCount from the previous change. So let's stop super complicated
things and just do a bit simpler form. This patch cleans up
backtrackable / non-backtrackable difference and basically assume that
we need to do backtrack in FixedCount parentheses all the time (e.g.
/(a+){3}b/). We removed weird code reseting m_reentry in the
backtracking side.
Test: JSTests/stress/regexp-variable-counted-parentheses-with-min.js
* JSTests/stress/regexp-variable-counted-parentheses-with-min.js: Added.
