7d6c2e1811
Builtin floating-point number classification functions:
- __builtin_isnan,
- __builtin_isinf,
- __builtin_finite, and
- __builtin_isnormal
now are implemented using `llvm.is_fpclass`.
This change makes the target callback `TargetCodeGenInfo::testFPKind`
unneeded. It is preserved in this change and should be removed later.
