Emit warning about infinite loop if for loop range starts with infinite value.
* pt-eval.cc (execute_range_loop): Check base of range, in addition to limit of
range, for infinite value and emit warning if found.
* for.tst: Add tests for new behavior. Recode tests so that they don't emit
warnings if file 'for.tst' is tested outside of test suite.
