Fix expression type for compressed assignment statements.
...
A compressed assignment statement should give exactly the same
result as the equivalent uncompressed statement. This means
that the type (signed/unsigned) of the LHS affects the type of
the RHS expression (unlike in normal assignments). We need to
take care that bit/part selects and concatenations are correctly
identified as unsigned values, even in the cases where they
reduce to a single whole signal.

Fix lval extension for compressed assignment in constant function.
...
The type of extension (zero/sign) is determined by the expression
type, not the operand type, so we need to cast to the expression
type before extending the value.

Fix cleanup of NetEvWait class.

The destructor needs to delete the stored NetEvent objects. Failure
to do this was causing a compiler crash after synthesis if the

Synthesis rework.
...
Synthesis could only handle relatively simple conditional constructs.
This rework aims to make it handle anything the user can throw at it
(or output a sensible message as to why it can't).

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.
