2023-08-24vm1: improve function calling (#6)Marc Vertes
The "Enter" instruction has been removed and the frame pointer is now saved by the "Call" instruction. The "Return" instruction now takes the number of function input parameters as the second operand. It's used to return the output values at the correct place in the caller frame, no matter the number of input parameters. The tests and the code generator have been updated accordingly.
