Zachary Snow 84edbae503 preliminary scoped errors with approximate source location 
- scoped traversals can now raise errors which contain the path of the
  current scope and an approximate source location based on preceding
  trace comments, if available
- initially, this new error messaging has only been added for the
  illegal size cast checks in the TypeOf and Cast conversions
- error suite tests can provide a verbose mode expected source location

Zachary Snow f061e88214 cleanup error suite infrastructure 
- error suite runs in both regular and verbose mode
- add helper for extracting "flags" from test files
- common assertMatch, assertNotMatch helpers
- remove unused assertExists helper
- fix un-escaped wildcard in assert_deferred_nonzero.sv

Zachary Snow 40f66e0212 add type signatures for all parser rules 
This works around a compilation performance regression in GHC 9.0.1:
https://gitlab.haskell.org/ghc/ghc/-/issues/20261. This also speeds up
compilation on other versions.

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
