vm_core.h (rb_thread_t): pack small fields together
On a 64-bit system, this reduces rb_thread_t from 536 to 520 bytes. Depending on the allocation, this can reduce cacheline access for checking the abort_on_exception, report_on_exception and pending_interrupt_queue_checked flags. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64376 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
