[PATCH v3 0/1] MR67: vkd3d: Store a struct d3d12_descriptor_heap pointer in each CBV/SRV/UAV descriptor.

[Conor McCarthy (＠cmccarthy)]

The PE build of vkd3d uses Windows critical sections for synchronisation, and
these slow down on the very high lock/unlock rate during multithreaded
descriptor copying in Shadow of the Tomb Raider. This patch speeds up the
demo by about 8%. By comparison, using SRW locks in the allocators and
locking them for read only where applicable is about 4% faster.
