Move the remaining CheckedNumeric logic out of the macro

Moves the remaining run-time logic into template classes and functions.
It also eliminates a number of public interfaces used for tests, etc,
and unifies the handling of floating points and integers.

Add variadic helper functions for CheckedNumeric math operations

This introduces variadic template functions that accept two or more
arithmetic or CheckedNumeric arguments and return a CheckedNumeric.
The functions are:

 * base::CheckAdd() - addition
 * base::CheckSub() - subtraction
 * base::CheckMul() - multiplication
 * base::CheckDiv() - division
 * base::CheckMod() - modulous
 * base::CheckLsh() - left integer shift
 * base::CheckRsh() - right integer shift
