6c5a3ab8b2 Add ReadRespWithInvalidate to handle multi-level coherence situation 
where we defer a response to a read from a far-away cache A, then later
defer a ReadExcl from a cache B on the same bus as us.  We'll assert
MemInhibit in both cases, but in the latter case MemInhibit will keep
the invalidation from reaching cache A.  This special response tells
cache A that it gets the block to satisfy its read, but must immediately
invalidate it.

21a99af009 Update memtest results due to new deferred-target-promotion fix. 
Turned out this scenario was happening, but due to other activity,
the writable block returned by the ReadResp would get downgraded
or invalidated before the "unnecessary" ReadExResp/UpgradeResp
returned, thus avoiding triggering the assertion that led us to
catch this.
