cfd3b893be
Add support to handle attributes at module instantiation sites.
...
(* my_fancy_attribute *)
foobar1 foobar (clk(clk), rst(rst) ...);
- Modifies PGModule to hold the attribute map (can be verified with pform_dump)
- pform_make_modgate(s) bind the attributes from the parser to the above map
- The attributes from PGModule are inserted into the NetScope of that module
PGModule::elaborate_scope_mod_instances_
- Currently these attributes automatically make it into netlist
- These attributes are accessible via ivl_scope_attr_cnt and ivl_scope_attr_val
from ivl_target.h

Parse/elaborate class derivation
...
This gets us down to working classes, but does not yet implement
calls to the parent constructor, implicitly or explicitly.

Handle array assignment patters through pform.

This gets us to elaboration. In the process also fix up ivl_type_t
type comparisons to do deep type comparison.

8994ef1483
Implement class constructors.
...
Class constructors are the "new" method in a class description.
Elaborate the constructor as an ordinary method, but the only
way to access this method is to implicitly call it. The elaborator
will take the constructor call and generate a naked "new" expression
and implicit constructor method call with the object itself as the
return value.
