Regression
No
AddComponent<>() high GC usage
Each call of AddComponent<>() function invokes
AttributeHelperEngine::GetParentTypeDisallowingMultipleInclusion and
AttributeHelperEngine::GetRequiredComponents
each method uses MonoType::GetCustomAttributes, which allocates 0.7 KB to GC
How to reproduce:
1. Open attached project
2. Build project for standalone platform
3. Attach profiler to build
4. Spam 'v' in build to call AddComponent<>()
5. Profile the calls
Reproduced on: 5.6.1p1, 2017.1.0b6, 2017.2.0a1
