test/codegen: remove broken riscv64 test

This test is not executed by default (see #48247) and does not
actually pass. It was added in CL 346689. The code generation
changes made in that CL only change how instructions are assembled,
they do not actually affect the output of the compiler. This test
is unfortunately therefore invalid and will never pass.

Updates #48247.
