[Patch, fortran] [12/21] Remove coarray support in the scalarizer: Get cobounds without the scalarizer

[Mikael Morin]

This patch sets cobounds in a coarray's gfc_ss struct without relying on the
scalarizer doing it automatically.
The convention to have the bounds and cobounds stored in the loop::from
and loop::to arrays while calling gfc_get_array_type_bounds is not changed,
so we need to set the loop.from[n] and loop.to[n] "by hand".

OK?

        * trans-array.c (gfc_conv_expr_descriptor): Add out-of-the-scalarizer
        cobounds evaluation.
