    bpo-36710: Add PyInterpreterState.runtime field (GH-17270)
    
    Add PyInterpreterState.runtime field: reference to the _PyRuntime
    global variable. This field exists to not have to pass runtime in
    addition to tstate to a function.  Get runtime from tstate:
    tstate->interp->runtime.
    
    Remove "_PyRuntimeState *runtime" parameter from functions already
    taking a "PyThreadState *tstate" parameter.
    
    _PyGC_Init() first parameter becomes "PyThreadState *tstate".

Funny/not funny, I introduced the same bug and I fixed it in bpo-39877.
