[NFC][Py Reformat] Reformat lit.local.cfg python files in llvm
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.

[SimpleLoopUnswitch] Enable freezing of conditions by default.
This fixes a series of mis-compiles by SimpleLoopUnswitch.

My measurements showed no performance regression with -O3 on AArch64
in SPEC2006, SPEC2017 and a set of internal benchmarks.

Fixes #50387, #50430

Depends on D124251.

725400f993 [NFCI][SimpleLoopUnswitch] Adjust CostKind query
When getUserCost was transitioned to use an explicit CostKind,
TCK_CodeSize was used even though the original kind was implicitly
SizeAndLatency so restore this behaviour. We now only query for
CodeSize when optimising for minsize.

I expect this to not change anything as, I think all, targets will
currently return the same value for CodeSize and SizeLatency. Indeed
I see no changes in the test suite for Arm, AArch64 and X86.
