Some architectures cannot always report accurately what kind of floating-point exception triggered a floating-point exception trap. This can occur with fp exceptions occurring on lanes in a vector instruction on arm64 for example. Rather than have every architecture come up with its own way of describing such a condition, this patch adds a common FPE_FLTUNK si_code value to report that an fp exception caused a trap but we cannot be certain which kind of fp exception it was.
