native on: all

Double the scalar width of a signed fixed point value.

The reason a special widen for fixed point is needed is because the fixed point is defined relative to the most significant side. Widening increases precision, but doesn't extend the value range.

The natively available byte widths on all Cores are 1, 2, 4, 8, and on the high end also 16.
