The instruction sequence generated for 64-bit indirect calls on hppa does not clobber register %r1, so
the clobbers for this register can be removed.

Tested on hppa64-hp-hpux11.11 with no observed regressions.

	* config/pa/pa.md (call_val_reg_64bit): Remove "reg: DI " clobber from
	pattern and subsequent splitters.
	(call_val_reg_64bit_post_reload): Likewise.
