Revert "[RISCV] Add test coverage for upcoming change to zicond select lowering"
This reverts commit 0c28482d91dbc80fb26990d0b4fac2974a72322e.
This took out a ton of buildbots because the test fails in most
configurations. Ex:
1. https://lab.llvm.org/buildbot/#/builders/185/builds/23944
2. https://lab.llvm.org/staging/#/builders/192/builds/1542
