What are the reasons/motivation for this change?
There are a number of easy to fix warnings:

  1. comparison of integers of different signs: 'size_t' (aka 'unsigned long') and 'int' [-Wsign-compare]

Explain how this is achieved.

  1. Const::size() returns int, so change iterators that use it to auto instead of size_t. For cases where size is being explicitly cast to int, use the wrapper that we already have instead: Yosys::GetSize().

If applicable, please suggest to reviewers how they can test the change.
Check what/if any warnings still show up at the bottom of the "Files changed" tab and in the "Compiler testing" section of the checks

`Const::size()` returns int, so change iterators that use it to `auto` instead of `size_t`.

@povik Do you want me to tidy up the warnings in the aiger2 code?

Yes please

- Remove unused statics CONST_FALSE and CONST_TRUE (which appear to have been folded into the `Index` declaration as CFALSE and CTRUE).
- Assign default value of EMPTY_LIT to `a` and `b` for comparison ops.
- Tag debug only variables with YS_MAYBE_UNUSED, don't assign unused variables (but continue to call the function because it moves the file pointer).
