Force code generation in assembly generation smoke-tests

In llvm/llvm-project@7b23f413d1f76532825e470b523e971818d453ca , `.text`
started being suppressed from LLVM assembly in cases where it wasn't
strictly necessary. Currently, the sample functions in these two tests
are frequently decided to be IR-only functions, resulting in no code
generation, so LLVM drops the `.text` directive.

Adding `#[no_mangle]` forces these tests back to their original intent -
assembly code is generated, and so a `.text` directive is generated as
well.
