dmd-built dmd is faster that ldc-built dmd or gdc-built dmd?

I distinctly remember Daniel and me having to remove those 
functions from DDMD when we first got it to build with LDC 
during/after DConf 2015.

LDC definitely does not mark symbols as weak/comdat/etc. by 
default. However, the linker might not pull in an object file 
from a static library if the respective symbols have already been 
resolved using other files.
