RISC-V: Implement mask reduction.
This implements mask reductions by first counting the bits in the mask
(vcpop.m) and then comparing the resulting scalar against 0 or len.
gcc/ChangeLog:
* config/riscv/autovec.md (reduc_sbool_and_scal_<mode>): New
expander.
(reduc_sbool_ior_scal_<mode>): Ditto.
(reduc_sbool_xor_scal_<mode>): Ditto.
* config/riscv/riscv-protos.h (expand_mask_reduction): Declare.
* config/riscv/riscv-v.cc (expand_mask_reduction): New function.
