Rewrite the two-component arithmetic macros.

Previously they were not bit-for-bit equivalent to the one-component
versions. The new code is also simpler and easier to read because it
factors out some common sub-macros.

The x * a + y * b macro now only uses four multiplications - the
previous version used eight.
