Top level variables are moved sometimes

[Jason Beetham]

Description

Depending on what hooks exist for a type top level variables might be moved instead of copied:

type MyType = object
  a: int

proc `=destroy`(typ: MyType) = echo "Destroyed: ", typ.a

var t1 = MyType(a: 100)
var t2 = t1 # Should be a copy?

proc main() =
  t2 = t1
  echo t1
  echo t2

main()

Nim Version
