* Fix constants bound to redeclared function argsZachary Snow2020-12-261-5/+16
| | | | | | | | The changes in #2476 ensured that function inputs like `input x;` retained their single-bit size when instantiated with a constant argument and turned into a localparam. That change did not handle the possibility for an input to be redeclared later on with an explicit width, such as `integer x;`.
