dc71fc8290 * make sure live_start/end is never a tai_regalloc, as those can be 
removed by the register allocator and thus become invalid. This fixed
    make cycle with -Or for ppc, but I'm not sure what the warning on
    symsym.pas:1663 means. Since the tlocation change, even regular make
    cycle doesn't work anymore though...

real registers

d2a2aeac9f * supregset_reset clears 8kb of memory. However, it is being called in 
inner loops, see for example colour_registers. According to profile data
    this causes fillchar to be the most time consuming procedure.
    Some modifications done to make it clear less than 8kb of memory each
    call. Divides time spent in fillchar by two, but it still is the no.1
    procedure.

71202a141d * taicpu.is_same_reg_move() now gets a regtype parameter so it only 
removes moves of that particular register type. This is necessary so
    we don't remove the live_start instruction of a register before it
    has been processed
