Zachary Snow 306d71334b refactor sizing and truncation of integer literals
- use iverilog's -gstrict-expr-width throughout test suite
- add warnings for excess bits or padding zeroes in number literals
- add new --oversized-numbers parameter to retain support for unsized
  numbers wider than 32 bits
- localized use of oversized numbers to new truncate test suite which
  verifies the behavior of both modes, and compares against the known
  behavior of iverilog

Zachary Snow b2fe865e17 fix interface modport substitution strategy
The interface conversion no longer substitutes parameters immediately,
instead fully scoping modports and allowing hierarchical constants to be
resolved separately. This fixes an issue where struct parameters could
lose their type information during substitution. The conversion also now
handles renaming references to the module or interface top-level scope.

Zachary Snow 16a13ee915 fix cascaded generate block cast and scope resolution
- scoper item injection can no longer affect generate scoping
- cast conversion injects functions into the top level when possible
- cast conversion considers loop variables to be local
- `else if` generate blocks are still scopes at the current level

Zachary Snow 2eee536f62 enum conversion to handles additional scope conflicts
- substitute enum item values directly into usage sites rather than
  creating synthetic localparams
- substitution handles shadowing of expressions in enum item values
- disconnected scopes can reference conflicting enum items

Zachary Snow bfd0cee0dc improved handling of procedural for loops
- convert loops with no or many incrementations
- restrict AST node to only contain traditional initializations
- parser elaborates for loop decls into a synthetic block
- decl list codegen is now specific to parameter decl lists
- update jump conversion special cases for new representation
- first experiments with bimapM
