Tiny executables

Hi, I'm trying to integrate LDC into SlimD
(https://github.com/CyberShadow/SlimD).

1. I couldn't find an equivalent to DMD's -betterC, to avoid 
generating ModuleInfos. I thought that -fdata-sections and 
-ffunction-sections would make it unnecessary, however LDC still 
generates a .ctors section, which linkers don't discard.

2. How does one do incremental compilation and LTO with LDC? 
Clang has -emit-llvm, but ldc2.exe doesn't have such an option.

3. Do I understand correctly that LDC uses COFF object files, 
however uses gcc/ld for linking? Meaning that MinGW uses COFF 
files on Windows as well?
