Zachary Snow d335d2ff25 use UTF-8 across all platforms 
- all inputs are now decoded as UTF-8, regardless of the platform

Zachary Snow c17d859988 tolerate escaped vendor comments within macros 2021-08-16 18:22:04 -06:00
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
