[Patch, fortran] [03/21] Remove coarray support in the scalarizer: Simplify coarray descriptor setup.

[Mikael Morin <mikael dot morin at sfr dot fr>]

In gfc_conv_expr_descriptor, the code setting the descriptor cobounds (copied
from the non-coarray case) has unnecessary stuff irrelevant to coarrays:
as codimensions can't be transposed, the condition dim[n] == n is guaranteed
to hold true for the codimensions.
This patch removes unnecessary code based on that assumption.

OK?
