[clang] [clang][bytecode][NFC] Add CHECK markers for functions in test (PR #212699)

[Timm Baeder via cfe-commits]

https://github.com/tbaederr created https://github.com/llvm/llvm-project/pull/212699

We aren't testing the existence of the function in the output here, but without these markers, debugging test failures here can become very cumbersome.

Subject: [PATCH] [clang][bytecode][NFC] Add CHECK markers for functions in
 test

We aren't testing the existence of the function in the output here, but
without these markers, debugging test failures here can become very
cumbersome.
