.alias records.

Support timescales in design units that aren't inside a module.
...
SystemVerilog allows tasks, functions, and classes to be defined at the
root level or inside packages, so we can't rely on an enclosing module
being present to provide the timescale.

Handle mixed continuous and non-blocking assignments to same vector.
...
SystemVerilog allows a mixture of procedural and continuous assignments
to be applied to different parts of the same vector. The previous attempt
to make this work for non-blocking assignments was flawed (see preceding
fix for vvp_fun_part_pv::recv_vec4_pv). Instead, handle this case by
converting the non-blocking assignment into a delayed force statement,
which matches the way mixed continuous and blocking assignments are
handled.

Fix for GitHub issue #103 - vvp assertion failure on part select propagation.
...
The implementation of vvp_fun_part_pv::recv_vec4_pv was incorrect, and
propagated the incoming widths rather than the stored widths.

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.

Also initialise the stored operand values to 'bz instead of 'bx to get
the correct results when bits are not driven.

Delayed output of vvp dff to end of current time slot.
...
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.

Make .scope aware of return type, and extend %ret/vec4 operands

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