i965/vs: Fix GL_FIXED setup when a writemask is present.

By emitting code before generate_code(), we ended up in align1 mode
where writemasks don't exist, so we rescaled gl_Vertex.w and things
went badly.  By moving GL_FIXED support to the visitor, we end up with
normal codegen, and as a bonus the GL_FIXED setup ends up getting
printed appropriately in debug output.

Fixes gtf/GL2Tests/fixed_data_type
