[llvm] [CodeGen] Move llc-start-stop.ll test to X86 (PR #190151)

[Nikita Popov via llvm-commits]

https://github.com/nikic created https://github.com/llvm/llvm-project/pull/190151

The pass pipeline differs across targets, so make this test use
one specific pipeline, instead of trying to cater to cross-target
differences. Those differences are not relevant to the intent of
the test.
