Discard various ways in which gcc zeroes stack slots in the prologue.
So far in my investigations these have always been unnecessary, they
appear to be the result of missed optimisations by gcc, so cross
fingers and discard them. New variants have just shown up because I
started compiling the RTS with -optc-O2.
