Drop JIT_ISEQ_SIZE_THRESHOLD

Browse source 
Compiling everything seems to contributed to improving the final
performance in general. MJIT's compilation is slow anyway, especially
when you need to wait for JIT compaction.

This might make sense for short-time benchmarks like Optcarrot with
default parameters, but it didn't give benefits in my local environment.
