I don't want to have it in an interpreter Register, otherwise the
BytecodeArrayBuilder needs to know about it, which could get messy.
On ia32 it is already passed as a stack slot (effectively a stack located
argument to the Bytecode handler) so it isn't using an extra register
there. For
other architectures we have plenty of registers and I would prefer we have
it in
the standard context register, that way we don't need to load it every time
we
call another JS function.
