rb_io_buffer_t: pack structure
* include/ruby/io.h (rb_io_buffer_t): pack structure Reduces rb_io_t from 200 to 192 bytes, allowing rb_io_t to occupy one less cache line. [Feature #10050] n.b. this leaves a 4-byte hole after the `cbuf' field which may be used for future expansion. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@46884 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
