[llvm] [AArch64] Move peephole-sxtw.mir file to regression test directory (PR #100819)

[Dimitry Andric via llvm-commits]

https://github.com/DimitryAndric created https://github.com/llvm/llvm-project/pull/100819

In #96293 ("Remove superfluous sxtw in peephole opt") a file `peephole-sxtw.mir` was added to `llvm/lib/Target/AArch64/`, but it looks like this is a regression test file.

Move it to `llvm/test/CodeGen/AArch64/` which seems a more correct location.

Subject: [PATCH] [AArch64] Move peephole-sxtw.mir file to regression test
 directory

In #96293 ("Remove superfluous sxtw in peephole opt") a file
`peephole-sxtw.mir` was added to `llvm/lib/Target/AArch64/`, but it
looks like this is a regression test file.

Move it to `llvm/test/CodeGen/AArch64/` which seems a more correct
location.
