Two fixes needed:
- when searching for a base class, we need to look in the root scope
if the base class isn't found in the scope hierarchy
- the classes in the root scope need to be stored in an ordered
list, not a map, to ensure they are elaborated in the order they
were declared. Without this, the compiler may try elaborating an
extended class before its base class is known about.
Verilog spec has a very nasty system of macros jumping from
file to file, resulting in a global macro scope. We abosolutely
MUST track macro redefinitions and warn user about them.

If a thread becomes detached due to a join_any statement, that
thread must not attempt to join its parent, even if the parent
is waiting on a subsequent join statement.
This occurs when tgt-vvp attempts to generate a C4<..> constant
value with a bit width >= 65536. The actual failure occurs in the
StringHeap class, which originally supported a maximum string length
of 65535. This fix enables the StringHeap class to support any size
string (provided the system has sufficient memory).
Normally there is at most one signal attached to a vvp functor, but
due to port collapsing, there can be more than one. If these signals
are array words, we need to trigger vpi callbacks on all the associated
arrays when the functor value changes.
If there is a syntax error in the source code, pform_makegate may be
passed a null list of port connections. The error is already reported,
so we just need to ignore it.
Return and print an error if iverilog is unable to open dependencies
file. User can pass e.g path to existing directory in '-M' option,
which makes fopen to return NULL followed by crash in fclose.

- 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
