The code clearing specloop in gfc_conv_loop_setup would need some explanation.
This patch moves it to gfc_trans_create_temp_array (where the reason for
it are more clear) with a proper comment.
OK?

* trans-array.c (gfc_conv_loop_setup, gfc_trans_create_temp_array):
Move specloop arrays clearing from the former to the latter.
