pytype: stop excluding upgrade.py
The sole failure here was this, which is fixed by simply creating a set like the
caller, instead of a dict:
File "/mnt/c/Users/Matt/hg/mercurial/upgrade.py", line 73, in upgraderepo:
No attribute 'discard' on Dict[nothing, nothing] [attribute-error]
In Union[Any, Dict[nothing, nothing]]

#require execbit
$ hg init
$ echo a > a
$ hg ci -Am'not executable'
adding a
$ chmod +x a
$ hg ci -m'executable'
$ hg id

Make sure we notice the change of mode if the cached size == -1:
$ hg rm a
$ hg revert -r 0 a
$ hg debugstate
n 0 -1 unset a
$ hg status
M a
$ hg up 0
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg id

$ test -x a && echo executable -- bad || echo not executable -- good
not executable -- good
