Those opt_something instructions are worth refactoring. They tend to
have similar ways of executions. By extracting the common part,
generated vm_exec_core function shrinks from 26,816 bytes to 26,256
bytes (according to nm(1)).
This changeset introduces negligible performance impact. 3 repeated
runs of optcarrot benchmark on my machine resulted in:
before this: 28.813363684823557, 27.523907198440366, 27.292766121965400
after this: 28.174038497265080, 28.999513875020405, 29.621399800428065
in fps (greater==faster).
