YJIT: add heuristic to avoid compiling cold ISEQs (#8522)
* YJIT: Add counter to measure how often we compile "cold" ISEQs (#535)
Fix counter name in DEFAULT_COUNTERS
YJIT: add --yjit-cold-threshold, don't compile cold ISEQs
YJIT: increase default cold threshold to 200_000
Remove rb_yjit_call_threshold()
Remove conflict markers
Fix compilation errors
Threshold 1 should compile immediately
Debug deadlock issue with test_ractor
Fix call threshold issue with tests
* Revert exception threshold logic. Document option in yjid.md
* (void) for 0 parameter functions in C99
* Rename iseq_entry_cold => cold_iseq_entry
* Document --yjit-cold-threshold in ruby.c
