No, it describes the location of a symbol, not of a type.
Two symbols of the same type could be in different places (one in 
register, one in memory).
Think of location lists, too.
I could have two symbols of the same type in completely different places 
in memory and registers, at a given time (IE each in two different live 
ranges).

Also, part of the idea of using our own bytecode was being able to 
describe the location of complex things, such a vtable entry, in a 
portable way.
