[llvm] [SampleProfile][Test] Fix DISubroutineType debuginfo for two tests (PR #159640)

[via llvm-commits]

https://github.com/yonghong-song created https://github.com/llvm/llvm-project/pull/159640

During development of [1], I found two test failures

 -  llvm/test/Transforms/SampleProfile/ctxsplit.ll
 -  llvm/test/Transforms/SampleProfile/flattened.ll

due to incorrect DISubroutineType(s). This patch fixed the issue with proper types.
