Refactor OSR related code to prepare for "true" OSR.
- Make the compiler restore all callee-save registers.
- Make the compiler return any value in a core register: this simplifies
the current stub, and will also avoid having to look at the return
type (and reading the shorty) when returning to an nterp frame.
- Add OsrData and offsets of its members to be used by nterp.
