[PATCH] D73835: [IRBuilder] Virtualize IRBuilder

[David Chisnall via Phabricator via llvm-commits]

theraven added a comment.

Please can we have some perf comparisons for just -emit-llvm (not invoking any of the back-end infrastructure)?  Given the numbers so far, I'd expect these to also be in the noise, but even at -O0 a quite significant proportion of the compile time is spent after the stages that use IRBuilder.
