[ARM] PR target/71056: Don't use vectorized builtins when NEON is not available
PR target/71056
* config/arm/arm-builtins.c (arm_builtin_vectorized_function): Return
NULL_TREE early if NEON is not available. Remove now redundant check
in ARM_CHECK_BUILTIN_MODE.
* gcc.target/arm/pr71056.c: New test.
