Message : D3D11: Update cached dynamically recompiled programs. This change makes it so that when we need to recompile a program on a draw call, we also update the cache. It also streamlines the internal queries of the dynamic vertex and fragment shaders such that we only update the input and output signatures a single time per draw. This should also facilitate dirty bit implementations for the D3D11 back- end.
