mesa: Refactor bounding-box calculation out of _mesa_update_draw_buffer_bounds
Drivers that currently use _Xmin and friends to set their scissor
rectangle will need to use this code directly once they are updated for
GL_ARB_viewport_array.
v2: Use different bit-test idiom and fix mixed tabs and spaces. Both
were suggested by Ken.
