flags: introduce explicit testing for merging change to exec flag
It turns out that we do not seems to test the simple case for merging exec flag
changes. More advanced case are test (merging exec flag without a common
ancestors, merging with a symlink, etc…) but not the basic.
We are about introduce various fixes to merging flag change across renames,
having the most basic case tested first seems useful.
note: We are only testing "adding" an exec flag here, not removing it. We
introduce basic test on stable and will consolidate them on default.

$ cd base-repo
$ cat << EOF > a
> 1
> 2
> 3
> 4
> 5
> 6
> 7
> 8
> 9
> EOF
$ touch b
$ hg add a b
$ hg commit -m "initial commit"
$ cd ..
Testing merging mode change
===========================
setup
Change on one side, executable bit on the other
$ hg clone base-repo simple-merge-repo
updating to branch default

created new head
merge them (from the update side)
$ hg merge 'desc("make a executable, no change")'

(branch merge, don't forget to commit)
$ hg st

$ [ -x a ] || echo "executable bit lost"
merge them (from the chmod side)
$ hg up -C 'desc("make a executable, no change")'
