AFAIU, a call to a non-intrinsic `strictfp` function will be lowered to a call
instruction which is insensitive to FP optimisations and therefore safe outside
of a `strictfp` context. A constrained FP intrinsic, on the other hand, will be
selected to a platform-specific FP opcode which will be sensitive to FP
optimisations and should not be optimised around (this is what the `strictfp`
attribute communicates about a function body).
