[Patch, fortran] [26/66] inline sum and product: Update core structs: Move scalar struct.

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

This moves data::scalar field from gfc_ss to gfc_ss_info.
The expr subfield is renamed to value, as it is not the expression really,
it is a reference to a variable containing the pre-calculated value.
OK?
