Please run /azp run runtime-nativeaot-outerloop.

This is a bug that I already fixed on few other places earlier. The PC relative calculation must be relative to the actual instruction, which is -12 for movw and -8 for movt in this pattern. If the symbol is aligned just right, we would end up with the correct bottom half but off-by-one top half.
