tcg/i386: Support INDEX_op_dup2_vec for -m32
Unknown why -m32 was passing with gcc but not clang; it should have failed for both. This would be used for tcg_gen_dup_i64_vec, and visible with the right TB and an aarch64 guest. Reported-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
