hipe: Add pseudo_spill_f?move instructions
These pseudo instructions are added to all backends and allow spill slot
to spill slot move coalescing in a clean way.
They have regular move semantics, but contain an additional scratch
register to be used if both source and destination are spilled, and can
not be move coalesced.
Additionally, a register allocator callback
Target:is_spill_move(Instr, Context) is added which allows the spill
slot allocators to check for these instructions and try to coalesce the
spill slots the two temporaries are allocated to.
