97075b9982537b8d7cf7f921b8e0e667ffa7691c mem-cache: Selectively clear downstream pending
Until now, all deferred targets of an MSHR would be promoted together
as soon as the targets were serviced. When we promote deferred targets
we also clear the downstreamPending flag.
Due to the way we handle cache clean operations we might need to
promote only deferred targets that don't require writable, leaving
some targets as deferred. To allow for partial target promotion, this
change adds support for clearing the downstreamPending only for a
subset of a TargetsList.
