Need to commonize getting of the argument types for a method ebcause that code is shared with method invocation.
I can also probably just commonize the code I am writing and include stack
elements in there also in the base JIT. Instead of say
Object I can have a
fancy class that says the stack position and such.
It will be the same for literally every other architecture too. The only slight difference is the register selection and stack positions. So this would be best commonized to reduce duplicate code everywhere.
This also removes the need to have the initialize arguments method in the sub-JIT because it can be handled all by the code that fills the argument allocation information.
