Adds support for parameters to the BytecodeArrayBuilder and BytecodeGenerator.
Parameters are accessed as negative interpreter registers.

Adds implementations and tests for the following bytecodes:
- Add
- Sub
- Mul
- Div
- Mod
Also adds the Mod bytecode and adds support to BytecodeGenerator and
BytecodeArrayBuilder to enable it's use.
The current bytecodes always call through to the JS builtins. This also adds
LoadObjectField and CallJSBuiltin operators to the InterpreterAssembler.

Modifies the BytecodeArrayBuilder to create register operands which are
negative. This reduces the number of instructions to access registers
by the interpreter and allows us to use positive register operands to
access parameter values.
Adds a Register class to keep register usage typesafe and simplify the
convertion to bytecode operand values.
