[PATCH] D42411: [test-suite] Fix ambigous call to overloaded function isnan

[Simon Dardis via Phabricator via llvm-commits]

sdardis created this revision.
sdardis added a reviewer: hfinkel.

Older versions of glibc expose isnan as C99 macros and C++ functions, causing
a compilation failure of the CLAMR benchmark. Address this by explicitly calling
the c++ version of this function.
