Give min and max the kind of their untyped arguments, cover the evaluator (#25)

max(5, 4.0) has an untyped float type even though the integer wins, so
max(5, 4.0) / 2 * 10 is 25 and not 20. A right shift count is bounded by a
constant instead of the width of the value, which reaches the same result
without measuring it.

Tests cover every branch of the evaluator, including the error paths of each
operand position, and the package is back to full statement coverage.
