This CL adds the parsing of structs with names. The parsing of type
aliased structs remains to allow for migration to the new system. The
named struct format is always emitted.

This CL changes the AST dumping order to emit alias types before global

This CL moves the StructType name into the constructor of the struct
type instead of receiving through an accessor. The |set_name| accessor
is removed as it should not be needed anymore. All call sites have been
updated.
The vertex pulling transform was fixed to correctly register an alias
for the structure being created so it will be emitted.

Do this so we can generate the correct member name for a struct,

struct member names.
