iseq_inline_storage_entry: 24=>16 bytes on 64-bit
We may tag the running_thread pointer to avoid making the "once" struct
bigger than "struct iseq_inline_cache_entry".
This only saves a small amount with "valgrind ruby -e exit"
before:
total heap usage: 48,122 allocs, 19,248 frees, 8,110,149 bytes allocated
after:
total heap usage: 48,122 allocs, 19,253 frees, 8,099,197 bytes allocated
* insns.def (once): define and use fake RUNNING_THREAD_ONCE_DONE
pointer to indicate is->once.running_thread is done.
* vm_core.h (iseq_inline_storage_entry): remove done field,
allowing the union to be reduced from 24=>16 bytes on 64-bit
