CL# 2698724: UHT speed improvements: Code is now generated with tabs, rather than going through a separate Tabify step. Some expensive temporaries created during iteration and during iteration have been removed. FFunctionData::FunctionDataMap now uses unique ownership instead of shared ownership. TCString::Spc (and the new TCString::Tab) now uses a compile-time array instead of one generated at runtime with a static. TSet::Compact no longer rehashes if no compaction was performed. TArray assignment no longer reallocs to the same capacity. [CL 2698780 by Steve Robb in Main branch]
