bf47cf418a expr to bool is now it's own function.
* Now while and for loops work on ints and floats, like if statements
* This fixes the loop problem in #813

58dc2b719c better coroutine codegen, now passing first coro test

return from the coro

556f22a751 different way of fixing previous commit
get_fn_type doesn't need the complete parameter type, it
can just ensure zero bits known.

90598b4631 fix assert on self-referencing function ptr field
The construct `struct S { f: fn(S) void }` is not legal because structs
are not copyable but it should not result in an ICE.

Fixes #795.

This reverts commit c2f5634fb3df51622cf74f23b4ae0d4a7d2bbbe9.

It doesn't work. With this, LLVM moves the allocate fn call
to after llvm.coro.begin

4e43bde924 workaround for llvm: delete coroutine allocation elision
maybe this can be reverted, but it seems to be related
to llvm's coro transformations crashing.

9aa65c0e8e allow implicit cast from &const to ?&const &const
Allow implicit casts from n-th degree const pointers to nullable const
pointers of degree n+1.  That is:

    fn f() void {
        const s = S {};
        const p = &s;
        g(p);   // Works.
        g(&p);  // So does this.
    }

    fn g(_: ?&const &const S) void {  // Nullable 2nd degree const ptr.
    }

Fixes #731 some more.

40dbcd09da fix type_is_codegen_pointer being used incorrectly
The names of these functions should probably change, but at least
the semantics are correct now:
 * type_is_codegen_pointer - the type is either a fn, ptr, or promise
 * get_codegen_ptr_type -
   - ?&T and &T returns &T
   - ?promise and promise returns promise
   - ?fn()void and fn()void returns fn()void
   - otherwise returns nullptr
