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.

60b2031831 improvements to stack traces 
* @panic generates an error return trace
 * printing an error return trace no longer interferes with
   normal stack traces.
 * instead of ignore_frame_count, we look at the return address
   when you call panic, and that's the first stack trace function
   makes stack traces much cleaner - the error return trace
   flows gracefully into the stack trace

2e010c60ae Translate C now correctly converts ints, floats, ptrs and enums to bools 
* Boolean "and" and "or" should also work with these types.
* This new method also simplifies to output code.

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 
maybe this can be reverted, but it seems to be related
