rb_io_t: shrink from 216 to 200 bytes on 64-bit
* include/ruby/io.h (rb_io_t): shrink to 200 bytes from 216 on 64-bit This puts us within 8 bytes of being three cache lines instead of four lines on x86-64. This breaks the ABI. [Feature #10050] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@46883 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
