It's for dealing with qualified names, ie names with dots in them.
They specify the nature of the symbol which is before the dot.

where TFoo is a template --> DotTemplateExp(loc, bar, TFoo).

where Vfoo is a variable --> DotVarExp(loc, bar, Vfoo)

alias int quatsch; // quatsch is a type
quatsch.max --> DotTypeExp(loc, Id::max, quatsch);

If you look at parse.c, you can see how they are created. I recommend
looking at lexer.h and parse.c before trying to understand the rest of
the compiler.
