* generic/tclExecute.c (INST_EXPON): Native type overflow detection

        * tests/expr.test:      was completely broken.  Falling back on use of
        bignums for all non-trivial ** calculations until
        native-type-constrained special cases can be done carefully and
        correctly.  [Bug 1561260].
