vmwgfx: Add an option to enable rendercheck mode
Rendercheck mode is used to enable acceleration of all supported composite
operations, regardless of the current data location. The mode is off by
default, but could be turned on to test the hardware composite operation
implementation. Due to excessive data migration, rendercheck mode will be
slow.
