math: Add more details to the test driver output.
Add start and end indicators that identify the test being run in the verbose output. Better identify the tests for max errors in the summary output. Count each exception checked for each test. Remove double counting of tests for the check_<type> functions other than check_float_internal. Rename print_max_error and print_complex_max_error to check_max_error and check_complex_max_error respectively since they have side effects.
