I don't remember what --gc-sections is, but I guess it's something different. The code removed during the LTO is for example unreachable functions, or functions/methods, that once inlined are called from nowhere else, unused constants, etc. Here you can see an example on C code (in D1 it's the same):

Anyway, currently the LDC project is mostly sleeping.
