run coroutine tests only in Debug mode

Browse Source 
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.
