    Partially revert "LoongArch: Fix bug123807."

    This reverts the loongarch.cc change of the commit
    4df77a254263e96af1ab4d1288a35cff10c515a4.

    PR 123807 turns out to be a special case of the middle-end PR 124250.
    The previous ad-hoc fix is unneeded now since the underlying middle-end
    issue is fixed, so revert it but keep the test case.
