[ORC] Set ResolverBlockAddr in EPCIndirectionUtils::writeResolverBlock.

Without this, EPCIndirectionUtils::getResolverBlockAddr (and lazy compilation
via EPC) won't work.

No test case: lli is still using LocalLazyCallThroughManager. I'll revisit this
soon when I look at adding lazy compilation support to the ORC runtime.
