[test] These tests should check for codegen support.

These tests checks for x86_64-* targets and armv7-* targets. If LLVM is
not built with support for these targets, these tests will trip. It
appears the way to check for this is by REQUIRES CODEGENERATOR, so add
this to properly condition these tests.
