Ship tag check fix (#698)

The previous implementation of the sampler-set tag check mechanism was
convoluted, and would result in false matches / false mismatches under
some cache configurations.

This pr simplifies the check to the block number, functionally
equivalent to what should have been implemented but far simpler and
avoids any confusion or potential bugs by introducing additional slicing
to remove variable amounts of set index and sampler index bits.

A test was added to ensure the matcher was behaving properly.

Fixes issue raised in #697
