    cmd/compile: combine stores into larger widths · 217c2849

    Combine stores into larger widths when it is safe to do so.
    
    Add clobber() function so stray dead uses do not impede the
    above rewrites.
    
    Fix bug in loads where all intermediate values depending on
    a small load (not just the load itself) must have no other uses.
    We really need the small load to be dead after the rewrite..
    
    Fixes #14267
