Use cvt_op to save intermediate type operand instead of "subtle" vec_dest.
When there're multiple operands in vec_oprnds0, vec_dest will be
overwrited to vectype_out, but in multi_step_cvt case, cvt_type is
expected. It caused an ICE when verify_gimple_in_cfg.
gcc/ChangeLog:
PR tree-optimization/110371
PR tree-optimization/110018
* tree-vect-stmts.cc (vectorizable_conversion): Use cvt_op to
save intermediate type operand instead of "subtle" vec_dest
for case NONE.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/pr110371.c: New test.
