wanglei a5c90e48b6 [LoongArch] Switch to the Machine Scheduler (#83759)
The SelectionDAG scheduling preference now becomes source order
scheduling (machine scheduler generates better code -- even without
there being a machine model defined for LoongArch yet).

Most of the test changes are trivial instruction reorderings and
differing register allocations, without any obvious performance impact.

This is similar to commit: 3d0fbafd0b
