    [maglev] Use RegList for free registers · 31abbcfb
    Leszek Swirski authored
    Store the free registers as a RegList rather than stack of Register
    values. This allows us to simplify some of the register freeing logic,
    including passing the current free set to nodes for use as temporaries.
    
    Drive-by: Replace ALWAYS_ALLOCATABLE_GENERAL_REGISTERS with
    ALLOCATABLE_GENERAL_REGISTERS, which is the more general list (the former
    is an implementation detail for optionally reserving a register for
    the cage register).
