    [turbofan] Add MachineType to LinkageLocation · 3e2085eb
    danno authored
    By adding MachineType to LinkageLocation, it is possible not only to reason
    about the location of a LinkageLocation on the stack, but also about it's
    size. This will be useful in follow-on CLs that attempt to merge some of the
    parameter passing logic of tail calls and normal (non-tail) calls.
    
    As a nice side-effect, it is no longer necessary to separately keep a
    MachineSignature in a CallDescriptor, because the MachineTypes contianed in
    LinkageLocation for all of the Descriptor's parameters and return types are
    sufficient. This CL therefore removes the MachineSignature from the
    CallDescriptor and adjusts all the calling code accordingly, simplifying and
    de-duplicating code in a bunch of places.
