/* When translating Vulkan access flags to which cache is accessed
 * (CCU/UCHE/sysmem), we should take into account both the access flags and
 * the stage so that accesses with MEMORY_READ_BIT/MEMORY_WRITE_BIT + a
 * specific stage return something sensible. The specification for
 * VK_KHR_synchronization2 says that we should do this:
 *
 *    Additionally, scoping the pipeline stages into the barrier structs
 *    allows the use of the MEMORY_READ and MEMORY_WRITE flags without
 *    sacrificing precision. The per-stage access flags should be used to
 *    disambiguate specific accesses in a given stage or set of stages - for
 *    instance, between uniform reads and sampling operations.
 *
 * Note that while in all known cases the stage is actually enough, we should
 * still narrow things down based on the access flags to handle "old-style"
 * barriers that may specify a wider range of stages but more precise access
 * flags. These helpers allow us to do both.
