runtime: fix data race during Itab hash update/lookup
...
The data race is on newly published Itab nodes, which are
both unsafely published and unsafely acquired. It can
break on IA-32/Intel64 due to compiler optimizations
(most likely not an issue as of now) and on ARM due to
hardware memory access reorderings.
