global variable initialized to a global constant is actually a mutable reference

[thejoshwolfe]

possibly a regression from result location.

const std = @import("std");

const Foo = struct {
    x: i32,
    y: i32,
};

/// should be constant
const c = Foo{ .x = 1, .y = 1 };

/// should be a copy of c, not a reference to it.
var v: Foo = c;

test "asdf" {
    var p = &c;
    std.testing.expect(p.x == c.x);
    // this erroneously modifies c at runtime:
    v.x = 2;
    // comptime c.x is 1, but runtime p.x is actually 2:
    std.testing.expect(p.x == c.x);
}

this works now
