* pa.h (LEGITIMIZE_ADDRESS, SYMBOL_REF case): Emit a sequence
	which will cause "addil" instructions to be emitted instead of
	"ldil; add" sequences.
	* pa.h (TARGET_KERNEL): New switch "-mkernel" which forces gcc to
	avoid "ldil; add" sequences with %r27 and instead generate "addil"
	sequences.  This avoids a HPUX linker bug when compiling kernels.

* 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.
