backport: pa.h (MAX_PCREL17F_OFFSET): Define. 

Backport from mainline:
	2012-06-03  John David Anglin  <dave.anglin@nrc-cnrc.gc.ca>

	* config/pa/pa.h (MAX_PCREL17F_OFFSET): Define.
	* config/pa/pa.c (pa_attr_length_millicode_call): Use
	MAX_PCREL17F_OFFSET instead of fixed offset.
	(pa_attr_length_call): Likewise.
	(pa_attr_length_indirect_call): Likewise.
