DMD: https://github.com/D-Programming-Language/dmd/blob/v2.062/src/e2ir.c#L2431

GDC: https://github.com/D-Programming-GDC/GDC/blob/master/gcc/d/d-elem.cc#L100

LDC: https://github.com/ldc-developers/ldc/blob/master/gen/arrays.cpp#L812

It's all reimplementations of the same thing. I guess there was a reason for
why the layer of abstraction was chosen to be this high, but in this situation
it's not doing anyone any favors.

Well, I guess that now that DMD is faster than both GDC and LDC at something,
the burden is on those compilers' maintainers to catch up with it :)
