Remove eval_expr during PEBinary elaboration
...
Turns out that call to eval_expr is redundant, and in degenerate
situations can lead to so many wasteful calls to eval_expr that
elaboration performance suffers dramatically.

Follow non-canonical bit numbering.

The signal bit numbering should be used for signals. This is
necessary for .model ports because the user specified numbers
are part of the interface, but once that is done, it is trivial
to follow it internally as well.

Add support for a generate scope to vvp and the vpi routines.
...
Instead of just translating a generate scope to a named begin/end scope
this patch creates a generate specific scope (vpiScopeGenerate) that is
of the vpiGenScope type. This may not match the standard 100%, but does
allow the FST dumper to denote generate scopes differently than the
other scope types. Most of the VPI code treats a vpiGenScope just like a
named block so only the FST dumper should have different behavior.
