Reverts llvm/llvm-project#146226 The MPFR test uses `mpfr_asinpi` which requires MPFR 4.2.0 or later, but the Buildbots are running an older version of MPFR. See https://lab.llvm.org/buildbot/#/builders/104/builds/27743 for example. I said I was going to revert the PR until we have a workaround for older versions of MPFR, but then I forgot and I just disabled the entrypoints which doesn't fix the Buildbot builds.
