Results of `math` Functions Should be Assignable as Constants

[NotsoanoNimus]

This may be a difficult issue due to the way the @LinkMath attribute works (I literally have no idea), but I'm trying to do the following:

module some_module { F };

const A_CONST = 12 + 2 * math::log2(F / 25);

which results in:

16: const MAX_ROUNDS = 12 + 2 * math::log2(F / 25);
                                ^^^^^^^^^^^^^^^^^^
(localtesting.c3:16:29) Error: Cannot call macro with '@links' outside of a function.

It seems this should be easily assignable into a constant value given the context.

This should be fixed now, please try it.
