Revert "teach inductor to handle floor (#94341)"
This reverts commit e7df9aaec83648445f6cae3412b5b4038fbbe400.
Reverted https://github.com/pytorch/pytorch/pull/94341 on behalf of https://github.com/huydhn due to Sorry for reverting your PR, but the CudaTest failure looks related. It fails on both PR and trunk https://hud.pytorch.org/pytorch/pytorch/commit/e7df9aaec83648445f6cae3412b5b4038fbbe400
