S/390: Add builtins for efpc and sfpc
gcc/ChangeLog:
* config/s390/s390.c (enum s390_builtin):
Add S390_BUILTIN_S390_SFPC and S390_BUILTIN_S390_EFPC.
(code_for_builtin): Add CODE_FOR_s390_sfpc and CODE_FOR_s390_efpc.
(s390_init_builtins): Generate new builtin functions.
* config/s390/s390.md (UNSPECV_SFPC, UNSPECV_EFPC): New constants.
(s390_sfpc, s390_efpc): New pattern definitions.
