* trans-array.c (gfc_trans_create_temp_array): If n is less
than the temporary dimension, assert that loop->from is
zero (reverts to earlier versions). If there is at least one
null loop->to[n], it is a callee allocated array so set the
size to NULL and break.
(gfc_trans_constant_array_constructor): Set the offset to zero.
(gfc_trans_array_constructor): Remove loop shifting around the
temporary creation.
(gfc_conv_loop_setup): Prefer zero-based descriptors if
possible. Calculate the translation from loop variables to
array indices if an array constructor.

* trans-array.c (gfc_trans_create_temp_array): If size is NULL
use the array bounds for loop->to.
