[PATCH] testsuite: Use noipa and noinline attributes for pr95115 test

[Xi Ruoyao via Gcc-patches]

They prevent the compiler from deeming the NaN result "unused" and
remove the calculation raising INVALID exception. See the discussion
in PR107608 for details.

Tested on x86_64-linux-gnu where the change fixes the test failure.
Ok for trunk?
