	* pa.c (emit_move_sequence): When making a reference to the data
	space before reload, emit an insn sequence which is much more
	likely to create "addil" instructions rather than "ldil; add"
	sequences.  Doing so greatly reduces the chance of running into a
	HPUX linker bug when compiling kernels.
