draw: fix/improve dirty state validation
This patch does two things:
1. Constant buffer state changes were broken (but happened to work by
dumb luck). The problem is we weren't calling draw_do_flush() in
draw_set_mapped_constant_buffer() when we changed that state. All the
other draw_set_foo() functions were calling draw_do_flush() already.
2. Use a simpler state validation step when we're changing light-weight
parameter state such as constant buffers, viewport dims or clip planes.
There's no need to revalidate the whole pipeline when changing state
like that. The new validation method is called bind_parameters()
and is called instead of the prepare() method. A new
DRAW_FLUSH_PARAMETER_CHANGE flag is used to signal these light-weight
state changes. This results in a modest but measurable increase in
FPS for many Mesa demos.
