Fix initialisation of vvp symbol table values.
...
In 64-bit Windows, an unsigned long is 32 bits, so initialising the num
member of the union did not properly initialise the ptr member. The num
member isn't actually needed, so eliminate it.

Implement %cmp/ne and %cmpi/ne
...
These pull in the inversion of the output flags so that they more
efficiently implement != and !==, without %flag_inv instructions.

Add the %cmp/e instructions, and put them to use.
...
When testing for == and ===, there is no need to also calculate <,
so it makes sense to have a special instruction for these cases.

Implement the %parti/X instructions

Also update some more instructions to more optimally work with
the vec4 stack.

Allow class properties to be arrayed.

This adds the runtime support for class properties that are classes
to be arrayed. Add a means to define the dimensions of a property
in the vvp format, and add functions for setting/extracting elements
of a property.

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.
