Log:
rs6000: wv -> v+p7v
"wv" is "v", but only if VSX is enabled (otherwise it's NO_REGS). So
this patch sets "isa" "p7v" to all alternatives that used "wv" before
(and that do not already need a later ISA), and changes the constraint.
* config/rs6000/constraints.md (define_register_constraint "wv"):
Delete.
* config/rs6000/rs6000.c (rs6000_debug_reg_global): Adjust.
(rs6000_init_hard_regno_mode_ok): Adjust.
* config/rs6000/rs6000.h (enum r6000_reg_class_enum): Delete
RS6000_CONSTRAINT_wv.
* config/rs6000/rs6000.md: Adjust.
* config/rs6000/vsx.md: Adjust.
* doc/md.texi (Machine Constraints): Adjust.
