84e952c230 fix await multithreaded data race
coro return was reading from a value that coro await was
writing to. that wasn't how it was designed to work, it
was an implementation mistake.

this commit also has some work-in-progress code for fixing
error return traces across suspend points.

58dc2b719c better coroutine codegen, now passing first coro test

4e43bde924 workaround for llvm: delete coroutine allocation elision
maybe this can be reverted, but it seems to be related

4ac6c4d6bf workaround llvm coro transformations

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

f11b948019 allow implicit cast from S to ?&const S
Allow implicit casts from container types to nullable const pointers to
said container type.  That is:

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

    fn g(_: ?&const S) void {  // Nullable const pointer.
    }

Fixes #731.

0845cbe277 name types inside functions after variable
Before this commit:

    fn f() []const u8 {
        const S = struct {};
        return @typeName(S);  // "f()", unexpected.
    }

And now:

    fn f() []const u8 {
        const S = struct {};
        return @typeName(S);  // "S", expected.
    }

Fixes #675.
