2020-04-13	Unify vm benchmark prefixes to vm_ (#3028)	Takashi Kokubun
	The vm1_ prefix and vm2_ had had special meaning until 820ad9cb1d72d0897b73dae282df3793814b27e8 and 12068aa4e980ab32a0438408a519030e65dabf5e. AFAIK there's no special meaning in vm3_ prefix. As they have confused people (like "In `benchmark` what is difference between `vm1_`, `vm2_` and `vm3_`"), I'd like to remove the obsoleted prefix as we obviated that two years ago.

2019-09-19	reuse cc->call	卜部昌平
	I noticed that in case of cache misshit, re-calculated cc->me can be the same method entry than the pevious one. That is an okay situation but can't we partially reuse the cache, because cc->call should still be valid then? One thing that has to be special-cased is when the method entry gets amended by some refinements. That happens behind-the-scene of call cache mechanism. We have to check if cc->me->def points to the previously saved one.
