refactor(arithmetic): specify FP overflow and domain options for rema…

…ining ops (#269)

Addition, substraction, multiplication and division were added before we'd settled on / had
conversations around what made sense for floating-point overflow and domain error options.  Adding
in appropriate overflow options for those four ops and also adding the appropriate domain error
option for division.

BREAKING CHANGE: Options SILENT, SATURATE, ERROR are no longer valid for use with floating point
arguments to add, subtract, multiply or divide
