mesa: Move the mvp_with_dp4 flag to ShaderCompilerOptions.
This flag essentially tells the compiler whether it prefers dot products or multiply/adds for matrix operations. As such, ShaderCompilerOptions seems like the right place for it. This also lets us specify it on a per-stage basis. This patch makes all existing users set the flag for the Vertex Shader stage only, as it's currently only used for fixed-function vertex programs. That will change soon, and I wanted to preserve the existing behavior. Signed-off-by: Kenneth Graunke <> Reviewed-by: Ian Romanick <> Reviewed-by: Eric Anholt <>
