    cmd/compile: make [0]T and [1]T SSAable types · 74144506
    Keith Randall authored
    We used to have to keep on-stack copies of these types.
    Now they can be registerized.
    
    [0]T is kind of trivial but might as well handle it.
    
    This change enables another change I'm working on to improve how x.(T)
    expressions are handled (#17405).  This CL helps because now all
    types that are direct interface types are registerizeable (e.g. [1]*byte).
    
    No higher-degree arrays for now because non-constant indexes are hard.
    
    Update #17405
