mesa/marshal: add custom marshalling for glNamedBuffer(Sub)Data
These entry points are used by Alien Isolation and caused synchronization with glthread. The async marshalling implementation is similar to glBuffer(Sub)Data. However unlike Buffer(Sub)Data we don't need to worry about EXTERNAL_VIRTUAL_MEMORY_BUFFER_AMD, as this isn't applicable to these DSA variants. Results in an approximately 6x drop in glthread synchronizations and a ~30% FPS jump in Alien Isolation (Medium preset, Athlon 860K, RX 480). Reviewed-by: Timothy Arceri <>
