Zachary Snow 1419c8761c Fix constants bound to redeclared function args 
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;`.

Zachary Snow c7ceed3fd3 Simple support for %l format specifier 
Yosys doesn't support libraries, so this provides the same behavior as
%m, as some other tools have opted to do.
