In the test case, with extreme amounts of unreachable code, we could remove a BBJ_CALLFINALLY that was not marked as `BBF_DONT_REMOVE`. If so, it would not go down the code path that handles removing the BBJ_ALWAYS pair of the BBJ_CALLFINALLY, which handles removing the `BBF_FINALLY_TARGET` flag on Linux/arm. Refactor the code so unreachable BBJ_CALLFINALLY/BBJ_ALWAYS pairs are always handled. Fixes dotnet#94680
