Issue 2098: solve() must checks assumptions on symbols, to filter solutions.

For example, if x = Symbol('x', real=True), solve(x**2 + 1, x) should not
    return any solution.

    NOTA: Presently, assumptions aren't checked when:
            o `solve()` input involves relationals or bools.
            o if no symbols are given for a nonlinear system of equations,
              and there is an ambiguity concerning the variable the system
              was actually solved for.
One should agree to `solve()` output format before adressing these issues.

We have

In [17]: (-y - 3).is_finite
