This patch adds foundational support by making two functions that handle
predication policies visibly globally.
gcc/ChangeLog:
* config/riscv/riscv-vector-builtins.cc (get_tail_policy_for_pred):
Remove static declaration to to make externally visible.
(get_mask_policy_for_pred): Ditto.
* config/riscv/riscv-vector-builtins.h (get_tail_policy_for_pred):
New external declaration.
(get_mask_policy_for_pred): Ditto.
