fix(runtime-core): always set invalid vnode type (#820)

Currently, when a component used is not properly registered, we have a warning and the vnode type is set to a Comment type in DEV mode. But in prod mode, we have no default value, making such an application broken and throw a strange error (`can not read _isSuspense of undefined`).

This commit avoids such an error in prod mode (as it is currently the case in Vue 2.x).

fix(build): remove __RUNTIME_COMPILE__ flag

behavior should be consistent in all builds. fix #817

refactor(Suspense): remove unnecessary casts (#819)
