Tolerate incorrect return type for 'isinf' and 'isnan' in tests.

Summary:
GLIBC recently removed the incorrect `int isinf(double)` and `int isnan(double)` overloads in C++11 and greater. This causes previously `XFAIL: linux`  tests to start passing.

Since there is no longer a way to 'XFAIL' the tests I choose to simply tolerate this bug.
