Florian Hahn a4573ee38d [LoopUnroll] UnrollRuntimeMultiExit takes precedence over TTI. (#134259) ...

Update UnrollRuntimeLoopRemainder to always give priority to the
UnrollRuntimeMultiExit option, if provided.

After ad9da92cf6 (https://github.com/llvm/llvm-project/pull/124462),
we would ignore the option if the backend indicates multi-exit is profitable.
This means it cannot be used to disable runtime unrolling.

To be consistent with canProfitablyRuntimeUnrollMultiExitLoop, always
respect the option.

This surfaced while discussing https://github.com/llvm/llvm-project/pull/131998.
