Hello,
This patch depends on the -mcpu=future patch and will be upstreamed
after that patch is upstreamed.
Bootstrapped and regtested on powerpc64le-linux-gnu.
Thanks and regards,
Kishan Parmar
Changes from v1:
1. Remove the 'future' attribute; use stanza-based gating only.
Add support for gating rs6000 built-ins on a new target predicate
"future", corresponding to -mcpu=future.
Extend rs6000-gen-builtins.cc and rs6000-builtin.cc to recognize
[future] as a valid built-in gating predicate to enable defining new
built-ins in .bif files.

gcc/ChangeLog:
* config/rs6000/rs6000-builtin.cc (rs6000_invalid_builtin): Handle
ENB_FUTURE and issue diagnostic requiring -mcpu=future.
(rs6000_builtin_is_supported): Return TARGET_FUTURE for
ENB_FUTURE built-ins.
* config/rs6000/rs6000-gen-builtins.cc (enum bif_stanza): Add
BSTZ_FUTURE for future.
(write_decls): Add ENB_FUTURE in bif_enable enum of generated header
file.
