`-prof` increases codegen cost significantly
For a long time I've noticed that profiled compilation is noticeably slower than vanilla compilation, even when no cost-centers are added.
To characterise this I built the Cabal library with and without -prof:

On enabling -ddump-timings I noticed that the largest increase is cost seems to come in CodeGen, which frequently allocates between 10% and 100% more when profiling is enabled:
