An invalid-descriptor fault check of a GPU-descriptor buffer access, and the
swizzle-selector check of a formatted load, is not emitted when an identical
check on the same descriptor under the same execution guard sits earlier in
the same IR block or in a dominating block. The fault record, the invocation
stop and the host error stay the same; only the pc stored for a fault that two
invocations race to record can differ. APS5_NO_FAULT_CHECK_DEDUP restores every
check.
