Subject: [ruby-core:87823] [Ruby trunk Bug#14892] r63763 breaks	-DMJIT_FORCE_ENABLE=1

Issue #14892 has been updated by wanabe (_ wanabe).


Many cases (including `a, b = nil`) go well after r63863.
Now I found that there remain 2 issues at least.

1. `pc` is set to `next_pos` when insn is `opt_xxx` and `body->catch_except_p` is falsy.
   * ex. `1000.times { break if /a/ =~ "ab" && !$~[0] }`
2. `opt_aref_with` / `opt_aset_with` push `rb_str_resurrect(key)` when MJIT execution is cancelled, but it is unexpected for VM's `opt_aref_with` / `opt_aset_with`.
   * ex. `1000.times { Thread.current["a"] = {} }`

r63763 ("give up insn attr handles_frame") breaks -DMJIT_FORCE_ENABLE=1

(commit 6b534134a78e3e43c344682c3585e1abab015216 in git)
Related [Bug #14809] [Bug #14834]

Is this being worked on? I mentioned it in [ruby-core:87674],
"make test" fails in test_insns.rb for me on Debian 9 (x86 and amd64).
Not sure what's wrong.

Reverting that commit allows even "make exam" to pass for me.
