Max Bernstein	039f4139f8	ZJIT: Create delta debugging script to narrow JIT failures (#14041) ... Add support for `--zjit-allowed-iseqs=SomeFile` and `--zjit-log-compiled-iseqs=SomeFile` so we can restrict and inspect which ISEQs get compiled. Then add `jit_bisect.rb` which we can run to try and narrow a failing script. For example: plum% ../tool/zjit_bisect.rb ../build-dev/miniruby "test.rb" I, [2025-07-29T12:41:18.657177 #96899] INFO -- : Starting with JIT list of 4 items.
