Hot reload iteration times have been crippled ever since CL# 3332960, which was a fix for [Link Removed].

Steps to Reproduce
  • Load QAGameEditor.
  • Add a space to QATestActor.cpp.
  • Hit Compile in the editor.
  • Note in the output that UnrealHeaderTool gets rerun even though no header has changed.

Expected: hot reload occurs successfully without UnrealHeaderTool rerunning on .cpp file changes, and that the error in [Link Removed] does not recur.
