Use (better) guard for IEC559 code and constants

Clang doesn't defined __GCC_IEC_559, so we need to look at __STDC_IEC_559__. This is already implemented as COMPLETE_IEC559_SUPPORT in test_values.h, which we can reuse in the tests. For completeness, don't define named constants when their use is #ifdef'ed out. ChangeLog: * testsuite/tests/fpclassify.cc: Guard IEC559 special values with COMPLETE_IEC559_SUPPORT. * testsuite/tests/frexp.cc: Likewise.
