This is a follow-up to b71edfaa4ec3c998aadb35255ce2f60bba2940b0
since I forgot the lit.local.cfg files in that one.
Reformatting is done with `black`.
If you end up having problems merging this commit because you
have made changes to a python file, the best way to handle that
is to run git checkout --ours <yourfile> and then reformat it
with black.
If you run into any problems, post to discourse about it and
we will try to help.

Update the EarlyCSE tests to use opaque pointers.
Worth noting that this leaves some bitcast ptr to ptr instructions
in the input IR behind which are no longer necessary. This is
because these use numbered instructions, so it's hard to drop them
in an automated fashion (as it would require renumbering all other
instructions as well). I'm leaving that as a problem for another day.
The test updates have been performed using

As discussed in D86843, -earlycse-debug-hash should be used in more regression
tests to catch inconsistency between the hashing and the equivalence check.
