pa.h (enum processor_type): New enumeration describing the processor to schedule for (700, 7100, 7100LC).

	* pa.h (enum processor_type): New enumeration describing the
	processor to schedule for (700, 7100, 7100LC).
	(pa_cpu_attr, TARGET_OPTIONS, OVERRIDE_OPTIONS): Define.
	(pa_cpu_string, pa_cpu): Provide extern decls.
	* pa.c (pa_cpu, pa_cpu_string): Provide definitions.
	(override_options): New function.
	(pa_adjust_cost): Handle PROCESSOR_7100 and PROCESSOR_7100LC
	scheduling.  Handle anti-dependendy cases involving fp division
	and sqrt.  Handle output dependencies correctly.  Break TYPE_FPMUL
	into TYPE_FPMULSGL and TYPE_FPMULDBL.
	* pa.md (cpu attribute): New attribute.
	Clean up comments for PROCESSOR_700 scheduling info.  Slightly
	simplify.  Make conditional on PROCESSOR_700.
	Add comments and scheduling information for PROCESSOR_7100 and
	PROCESSOR_7100LC.  Set types for instructions which use the shifter
	to "shift".  Explicitly set lengths and types for all instructions.
	Break type "fpmul" into "fmulsgl" and "fpmuldbl".
