Currently `__FINITE_MATH_ONLY__` is set when `FiniteMathOnly`. And `FiniteMathOnly` is set when `NoHonorInfs` && `NoHonorNans` is true. But what happens one of the latter flags is false? To avoid potential inconsistencies, the internal option `FiniteMathOnly` is removed option and the macro `__FINITE_MATH_ONLY__` is set when `NoHonorInfs` && `NoHonorNans`.
