Log:
[67/77] Use scalar_mode in fixed-value.*

This patch makes the fixed-value.* routines use scalar_mode.
It would be possible to define special classes for these modes, as for
scalar_int_mode and scalar_float_mode, but at the moment nothing would
benefit from them.  In particular, there's no use case that would help
select between one class for all fixed-point modes versus one class for
fractional modes and one class for accumulator modes.
