[llvm-branch-commits] [clang] [SSAF] Remove UnsafeBufferUsageTest.h (PR #195201)

[Ziqing Luo via llvm-branch-commits]

https://github.com/ziqingluo-90 created https://github.com/llvm/llvm-project/pull/195201

The idea is that we do not want to have test-only functionality in any interface.
We have lit tests covering the removed unit test.

Subject: [PATCH] [SSAF] Remove UnsafeBufferUsageTest.h

The idea is that we do not want to have test-only functionality in any
interface.
