[Committed] Fix up one more autovectorizer testcase after my patch

I found another case where we use create_tmp_var instead of
vect_get_new_vect_var which we setup DECL_GIMPLE_REG_P correctly
already.  This was caught by the powerpc-darwin autotester and it does
not show up on i686-linux which is why I did not check it while
bootstrapping.

Committed as obvious after a quick build/test on powerpc-darwin.
Note the reason why I did a build and not a bootstrap is because this
code is not involved during bootstrap.

Thanks,
Andrew Pinski

ChangeLog:

	* tree-vect-transform.c (vect_permute_load_chain):
	Set DECL_GIMPLE_REG_P to true for the vect_perm_*
	temp variables.
