aarch64: Add a result_mode helper function
SME will add more intrinsics whose expansion code requires
the mode of the function return value. This patch adds an
associated helper routine.
gcc/
* config/aarch64/aarch64-sve-builtins.h
(function_expander::result_mode): New member function.
* config/aarch64/aarch64-sve-builtins-base.cc
(svld234_impl::expand): Use it.
* config/aarch64/aarch64-sve-builtins.cc
(function_expander::get_reg_target): Likewise.
