2019-08-06improve async function semanticsAndrew Kelley
* add safety panic for resuming a function which is returning, pending an await * remove IrInstructionResultPtr * add IrInstructionReturnBegin. This does the early return in async functions; does nothing in normal functions. * `await` gets a result location * `analyze_fn_async` will call `analyze_fn_body` if necessary. * async function frames have a result pointer field for themselves to access and one for the awaiter to supply before the atomic rmw. when returning, async functions copy the result to the awaiter result pointer, if it is non-null. * async function frames have a stack trace pointer which is supplied by the awaiter before the atomicrmw. Later in the frame is a stack trace struct and addresses, which is used for its own calls and awaits. * when awaiting an async function, if an early return occurred, the awaiter tail resumes the frame. * when an async function returns, early return does a suspend (in IrInstructionReturnBegin) before copying the error return trace data, result, and running the defers. After the last defer runs, the frame will no longer be accessed. * proper acquire/release atomic ordering attributes in async functions.
2019-08-05async functions have error return traces where appropriateAndrew Kelley
however the traces are not merged on `await` or async function calls yet. When an async function has an error set or error union as its return type, it has a `StackTrace` before the args in the frame, so that it is accessible from `anyframe->T` awaiters. However when it does not have an errorable return type, but it does call or await an errorable, it has a stack trace just before the locals. This way when doing an `@asyncCall` on an async function pointer, it can populate the args (which are after the `StackTrace`) because it knows the offset of the args based only on the return type. This sort of matches normal functions, where a stack trace pointer could be supplied by a parameter, or it could be supplied by the stack of the function, depending on whether the function itself is errorable.

* add implicit cast from `*@Frame(func)` to `anyframe->T` or `anyframe`. * add implicit cast from `anyframe->T` to `anyframe`. * `resume` works on `anyframe->T` and `anyframe` types.
