---------------------------------------------

Any type of merge/compaction goes through the same code path, so it is all the same...

> This issue is about fixing ImmutableMemStoreLAB#forceCopyOfBigCellInto.
> Following a comment in HBASE-19133 regarding a bug in ImmutableMemStoreLAB#forceCopyOfBigCellInto
(assuming this method is never called for an ImmutableMemStoreLAB, and just throwing an IllegalStateException
whenever called), the forceCopyOfBigCellInto method now performs the copy of big cells on
the first MSLABImpl in its mslabs linked-list.
