John Stiles 5c57e88d8f Redesign GrXfermodeFragmentProcessor to use one FP instead of two.
Previously, we had separate "ComposeOne" and "ComposeTwo" fragment
processors. These performed extremely similar roles, but varied in
the number of child FPs used, and treatment of the input color's alpha
channel.

This CL combines these two FPs into a single unified "Compose" fragment
processor. To avoid breaking many existing GMs, the semantics of the
prior FPs have been preserved as closely as possible. (Specifically, the
FP treads very carefully to ensure that the alpha channel handling
matches the old code, as dozens of GMs fail otherwise.)
