    testsuite: Enable the PR 87600 tests for LoongArch

    I'm going to refine a part of the PR 87600 fix which seems triggering
    PR 120983 that LoongArch is particularly suffering.  Enable the PR 87600
    tests so I'll not regress PR 87600.

    gcc/testsuite/ChangeLog:

            PR rtl-optimization/87600
