We also test them against the LLVM IR produced by classic codegen to verify the
LLVM IR produced by the CIR path. You can use adjacent test files as a
reference for that. Also, we try to keep the names of the test files the same
as classic codegen. So, you need to change the name of this file to
`rd-builtins.c`.
