We now store 3x3 matrices, and cache all
destination inversion, not just the matrix.
The 4x4's are still there to support existing APIs,
including the guard flag added for layout tests.
There will be tons of tiny diffs from the inversion
changes, both from inverting transfer functions and
from inverting the matrix.
This doesn't change the numbers I'm seeing in nanobench,
but it does move the matrix concat and tf invert way
down the profile.
