    Revert "[nvptx, libgomp] Update pr85381-{2,4}.c test-cases" [PR89713,
PR94392]

    In response to PR94392 commit 75efe9cb1f8938a713ce540dc3b27bc2afcd3fae
    "c/94392 - only enable -ffinite-loops for C++", this reverts PR89713
    commit 00908992f2a78f213d227aea8dbab014a1361df0, as apparently now again
    "empty oacc loops are" no longer "removed before expand".
