Yes, we should probably revisit these cases at some point. I wanted to cleanup
my noRTTI (fno-rtti option for gdc) branch for DMD but I thought we won't merge
big non-DDMD changes for 2.069 so I postponed that.

I think the most important thing really requiring TypeInfo might be class down
casts. I don't see how you can do that without some kind of RTTI. But we could
just use some minimal RTTI for that (As long as we can put a unique pointer for
every class in the vtable any kind of RTTI should work).

There's also some postblit related stuff where I think the compiler could
statically generate the necessary code. It was probably easier to implement it
in druntime using RTTI.
