Funny failed experiment of micro-optimizing values

[kchanqvq]

From what I read online it is said JS engines typically don't inline polymorphic function variables (like values, which has two possible values internals.mv and internals.pv). So I figure using a boolean flag isMV instead and do the casting with a (constant) function internals.mv(isMV, ...values) might speed things up.

Turns out it's slower. The Internet shall not be trusted!!!

Although I implemented apply codegen syntax (compile to spread arguments call fn(x,y,...z)) for this experiment, which could be useful later.
