Avi Kivity bef8e5e930 Merge "Don't invalidate row cache when adding GC SStable to SSTable Set" from Raphael

"
Garbage collected SSTables, created by incremental compaction process,
are being added to the SSTable set using a function that invalidates
row cache using the range of the SSTable itself. That's incorrect
because data in GC SSTables come from preexisting SSTables in set,
meaning the state of data isn't changed and so no need for
invalidation at all. Incorrect invalidation like this is a source of
read performance issues. This problem is fixed by including GC
SSTables to the descriptor which is used to specify changes to the
SSTable set, which is the correct thing to do given that a midway
failure could leave the set in an incorrect state.

Fixes #5956.
Fixes #6275.
