Out of order typedefs of structs

[jacob-carlborg]

Out of order typedefs of structs results in duplicated structs.

The following code:

typedef struct _Foo Foo;

struct _Foo
{
    int x;
};

Results in:

extern (C):

alias _Foo Foo;

struct _Foo
{
}

struct _Foo
{
    int x;
}

Should be:

extern (C):

alias _Foo Foo;

struct _Foo
{
    int x;
}
