Hexagon (gen_tcg_funcs.py): avoid duplicated tcg code on A_CVI_NEW
Hexagon instructions with the A_CVI_NEW attribute produce a vector value that can be used in the same packet. The python function responsible for generating code for such instructions has a typo ("if" instead of "elif"), which makes genptr_dst_write_ext() be executed twice, thus also generating the same tcg code twice. Fortunately, this doesn't cause any problems for correctness, but it is less efficient than it could be. Fix it by using an "elif" and avoiding the unnecessary extra code gen.
