As Bugzilla 35090 <https://bugs.llvm.org/show_bug.cgi?id=35090> reported, the rationale for using custom lowering SREM/UREM should no longer be true. At the IR level,  the div-rem-pairs pass rL312862 <https://reviews.llvm.org/rL312862> performs the transformation where the remainder is computed from the result of the division when both a required. We should now be able to lower these directly on P9 <https://reviews.llvm.org/P9>. And the pass also fixed the problem that divide is in a different block than the remainder.
This is a NFC patch to remove redundant code.
