[WIP] Better generator for CALL*

1

Depends on #298.

Support new call interface

4

- return values have been changed - return value isn't written to be a paramater but retrieved via `returndatacopy`

- [x] remove non-folded instructions [#213] - [ ] figure out how to do VM tests with hera - [x] make the c++ work with hera (to speed up tests)...

Split off #201.

Currently `CALL*` just drops the last two parametes which specify the output area and length. Tests should expect data to be written there so I'd think at some point tests...
