gas: Validate SFrame RA tracking and fixed RA offset

Verify all architectures participating in SFrame generation do define
the mandatory SFrame return address (RA) tracking predicate function
sframe_ra_tracking_p. Do so by explicitly not testing for the macro
SFRAME_FRE_RA_TRACKING as otherwise required.

Verify that architectures not using SFrame RA tracking specify a valid
fixed RA offset.

	RA tracking and fixed RA offset.
