rs6000: Delete the "wy" constraint
This replaces the "wy" constraint by "wa", with isa "p8v". It also

Delete.
* config/rs6000/rs6000.h (enum r6000_reg_class_enum): Delete
RS6000_CONSTRAINT_wy.
* config/rs6000/rs6000.c (rs6000_debug_reg_global): Adjust.
(rs6000_init_hard_regno_mode_ok): Adjust.
* config/rs6000/rs6000.md: Replace "wy" constraint by "wa" with "p8v".
Use "<Fisa>" as "isa" in all alternatives that use "<Fv2>".
(define_mode_attr Fisa): New.
* config/rs6000/vsx.md: Replace "wy" constraint by "wa" with "p8v".
