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

36eadb569a run coroutine tests only in Debug mode 
LLVM 5.0.1, 6.0.0, and trunk crash when attempting to optimize coroutine code.
So, Zig does not support ReleaseFast or ReleaseSafe for coroutines yet.
Luckily, Clang users are running into the same crashes, so folks from the LLVM
community are working on fixes. If we're really lucky they'll be fixed in 6.0.1.
Otherwise we can hope for 7.0.0.

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.

4e43bde924 workaround for llvm: delete coroutine allocation elision

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.
