Allow classes to reference declarations in their enclosing scope(s).
...
The original implementation made each class a root scope. They should
be added to the scope hierarchy just like any other declaration.

Parse and elaborate unique and priority case statements
...
The unique, unique0, and priority keywords can decorate case statements
to tell the run time (or synthesis) to do extra tests (or make extra
assumptions). These tests are not implemented in the vvp run time, but
now the decorations make it to the code generators.

Support separate compilation units in SystemVerilog.
...
The compilation unit scope is now treated as a specialised form of
package (with an automatically generated name). All items declared
outside a design element are added to the current compilation unit
package. Apart from when searching for a symbol, once we get into
elaboration we can treat these just like any other package.

604a62379c
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
function knows how to intialize the return value. We also need to
extend the %ret/vec4 to support writing parts of the return value.

When for example assigning to foo[<x>] within a contitional, and
doing synthesis, we need to create a NetSubstitute device to manage
the l-value bit selects.

Add synthesis support for casez statements.
...
This generates an EQZ LPM device that carries the case-z-ness to
the code generator.
Also add to the vvp code generator support for the EQZ device so
that the synthesis results can be simulated.
Account for the wildcard devices in the sizer.

This allows for syntax like a.b.c where a is a class with member
b, which is a class with member c, and so on. The handling is mostly
for the support of compound objects like classes.

...
Emit the elaborated class methods. Also generate root scopes to
represent the classes in order to hold the methods. These scopes
can also in the future be used to implement static properties.
