merge revision(s) 3e6e3ca2627b1aa71b17de902cc1b8188246a828: [Backport #20207] (#10299)
Correctly handle consecutive lookarounds (#9738)
Fix [Bug #20207]
Fix [Bug #20212]
Handling consecutive lookarounds in init_cache_opcodes is buggy, so it
causes invalid memory access reported in [Bug #20207] and [Bug #20212].
This fixes it by using recursive functions to detected lookarounds
nesting correctly.
