rG7d6449322ecb: [DebugInfo][test] Check specific func name to ignore codegen differences
Summary

We use CHECK-LABEL: define to divide input stream into functions,
this works well on most platforms.

But there are cases that some platforms (eg: AIX) may have different
codegen , especially for global constructor and descructors.

On AIX, the codegen will have two more functions: dtor_b,
finalize_b, which will fail the test.

The fix is to use specific function name so that we can safely ignore
those unrelated codegen differences.

Probably flesh that out a bit. Maybe define{{.*}}f11?
