Description:
[interpreter]: Changes to interpreter builtins for accumulator and register
file
registers.
Makes the following modifications to the interpreter builtins and
InterpreterAssembler:
- Adds an accumulator register and initializes it to undefined()
- Adds a register file pointer register and use it instead of FramePointer
to
access registers
- Modifies builtin to support functions with 0 regiters in the register
file
- Modifies builtin to Call rather than TailCall to first bytecode handler.
