    [codegen] Use ABI caller saved regs for Pop/PushCallerSaved · b9af74c8
    Leszek Swirski authored
    The set of registers used for Pop/PushCallerSaved is a superset of the
    ABI caller-saved registers. In the past it may have been the case that
    these extra registers had to be saved, but at this point
    Pop/PushCallerSaved is only used for fast C calls from JS, so we can
    rely on the C-compiled functions saving callee-saved registers
    correctly, and only save ABI-required registers ourselves.
