It actually looks like this is now more important with D145558 <https://reviews.llvm.org/D145558> applied (around 0.24% difference). Here is the impact when this patch is reverted: http://llvm-compile-time-tracker.com/compare.php?from=baec5155d5e0c5d8cc0a2f51bd7fa14f785a0093&to=68d93a1c2d58990d7cd96f0b826b944fcc7d86f3&stat=instructions

+ Reduce clutter of insertion code 
+ Address nits
