Kai Sasaki cb898e26f3 [mlir] Make the print function in CRunnerUtil platform agnostic (#86767) ...

The platform running on Apple Silicon does not seem to support the
negative nan. It causes the test failure where we explicitly specify the
negative nan bit pattern and check the output printed by the CRunnerUtil
function.

We can make the print function in the utility platform agnostic by using
the standard library functions (i.e. `std::isnan` and `std::signbit`) so
that we can run the test across platforms that do not support the
negative bit pattern.

I have added two test cases that would fail in the Apple Silicon
platform without print function changes.
