tile: create new math-tests.h header
The header makes tile use the new mechanisms for suppressing exception and rounding support (the ROUNDING_TESTS_xxx() and EXCEPTION_TESTS_xxx macros). More importantly, it also now sets SNAN_TESTS_PRESERVE_PAYLOAD to 0, since the tilegx fp hardware does not preserve NaN payloads.
