           Summary: Segfault(declaration.c) using struct with destructor

struct Bug6933 {
    int x = 3;
    ~this()     {  }
}

int test6933() {
    Bug6933 q;
    return 3;
}

static assert(test6933());

It's because interpret.c, getVarExp calls StructLiteralExp::semantic with NULL
scope. semantic sees there's a destructor, and converts it into:
(Bug7973 __tmp = Bug6973(), __tmp). This crashes because __tmp is a variable
with no scope. I don't understand why it does that transformation, it seems to
me to be in the wrong place.

In these commits:

https://github.com/D-Programming-Language/dmd/commit/746d98fb0daacbd6a9efab1da6aacd2d7b55b39f

https://github.com/D-Programming-Language/dmd/commit/0051ed8ea86472083ed205a4857399d1f8defd71

it's mitigated from a segfault to an rejects-valid with line number.
