Implement via expansion, so don't actually set TCG_TARGET_HAS_roti_vec.
For NEON, this is shift-right followed by shift-left-and-insert.

The three vector shift by vector operations are all implemented via
expansion. Therefore do not actually set TCG_TARGET_HAS_shv_vec,
as none of shlv_vec, shrv_vec, sarv_vec may actually appear in the
instruction stream, and therefore also do not appear in tcg_target_op_def.

Add registers and function stubs. The functionality
is disabled via use_neon_instructions defined to 0.
We must still include results for the mandatory opcodes in
tcg_target_op_def, as all opcodes are checked during tcg init.
