7272 – `out` section makes return type `const` in `return` statement

---
int* f() 
out { } // no errors with `out` section
body {
 immutable(int)* ptr;
 return ptr;
}
---
If `immutable(int)*` is changed to `immutable(void)*` we have the following error:
`Error: cannot implicitly convert expression (ptr) of type immutable(void)* to const(int*)` illustrating the issue. Note, that `typeof(f())` and `typeof(return)` are `int*`.
Maybe concerned with Issue 1313 

I've posted a patch to fix 1313, and confirmed that this is a dup of it.
