IBM Z: Introduce __LONG_DOUBLE_VX__ macro
Give end users the opportunity to find out whether long doubles are
stored in floating-point register pairs or in vector registers, so that
they could fine-tune their asm statements.
gcc/ChangeLog:
2020-12-14 Ilya Leoshkevich <iii@linux.ibm.com>
* config/s390/s390-c.c (s390_def_or_undef_macro): Accept
callables instead of mask values.
(struct target_flag_set_p): New predicate.
(s390_cpu_cpp_builtins_internal): Define or undefine
__LONG_DOUBLE_VX__ macro.
