Currently, we context allocate all parameters for generators. With this CL, we keep arguments on stack (unless they escape to inner closure) and copy them between the stack and the generator's register file on suspend/resume. This will save context allocation in most cases. Note: There is an asymmetry between suspend and resume. - Suspend copies arguments and registers to the generator. - Resume copies only the registers from the generator, the arguments are copied by the ResumeGenerator trampoline.
