Represents difference between two FPOptions values.
The effect of language constructs changing the set of floating point options is usually a change of some FP properties while leaving others intact. This class describes such changes by keeping information about what FP options are overridden.
The integral set of FP options, described by the class FPOptions, may be represented as a default FP option set, defined by language standard and command line options, with the overrides introduced by pragmas.
The is implemented as a value of the new FPOptions plus a mask showing which fields are actually set in it.
