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.

58dc2b719c better coroutine codegen, now passing first coro test 
we have to use the Suspend block with llvm.coro.end to
return from the coro

ad2a29ccf2 break the data dependencies that llvm coro transforms cant handle

6e2a67724c Revert "another llvm workaround for getelementptr" 
This reverts commit c2f5634fb3.

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.

See #727

4ac6c4d6bf workaround llvm coro transformations 
by making alloc and free functions be parameters to async
functions instead of using getelementptr in the DynAlloc block

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
