Allowing LDC to do cross-module optimisations (by adding the 
-singleobj flag) and make use of popcnt increased the performance 
by 47% for one specific benchmark, which should bring it into the 
same ballpark as GDC. See https://github.com/abulmo/amoeba/pull/2 
for more details.

PGO might still give the latter a bit of an edge, though, as 
LDC's implementation is still experimental and there is a lot of 
unused potential for making use of the profile data in LLVM's 
optimiser.
