Ian Lance Taylor ea5ac5a69b compiler,runtime: pass old slice's ptr/len/cap by value to growslice 
In the C calling convention, on AMD64, and probably a number of
    other architectures, a 3-word struct argument is passed on stack.
    This is less efficient than passing in three registers. Further,
    this may affect the code generation in other part of the program,
    even if the function is not actually called.
    
    Slices are common in Go and append is a common slice operation,
    which calls growslice in the growing path. To improve the code
    generation, pass the slice header's three fields as separate
    values, instead of a struct, to growslice.
    
    The drawback is that this makes the runtime implementation
    slightly diverges from the gc runtime.
