engine: refactor code to replace stores in separate function
In not all upgrades, we need to change the whole store. For example, when
upgrading repository to share-safe mode, we don't touch revlogs at all hence
store cloning and copying is not required.
The store replacing code needs to be made aware about what all has changed and
hence only copy/rename those things. To kickstart that, this patch moves
existing logic into a separate function.

# Base Revsets to be used with revsetbenchmarks.py script
#
# The goal of this file is to gather a limited amount of revsets that allow a
# good coverage of the internal revsets mechanisms. Revsets included should not
# be selected for their individual implementation, but for what they reveal of
# the internal implementation of smartsets classes (and their interactions).
#
# Use and update this file when you change internal implementation of these
# smartsets classes. Please include a comment explaining what each of your
# addition is testing. Also check if your changes to the smartset class makes
# some of the tests inadequate and replace them with a new one testing the same
# behavior.
#
# If you want to benchmark revsets predicate itself, check 'all-revsets.txt'.
#
# The current content of this file is currently likely not reaching this goal
# entirely, feel free, to audit its content and comment on each revset to
# highlight what internal mechanisms they test.
