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.

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

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
