Extended fix for GitHub issue #99 .
...
Most vvp functors need to support recv_vec4_pv. Any that are strength-aware
also need to support recv_vec8_pv. Note the simplifying assumption that is
documented in the base class recv_vec4_pv_ implementation.

Fix GitHub issue #99 - recv_vec4_pv not implemented for arithmetic functors.
...
Also initialise the stored operand values to 'bz instead of 'bx to get
the correct results when bits are not driven.

Flip-flops are generally modelled in behavioural code using non-blocking
assignments. This change makes the synthesised code behave the same as
the behavioural code. It's a more realistic model of a real flip-flop
too, which will always have some clock-to-output delay.

The .scope needs to be aware of return types so that the %call/vec4
