method.h: pack rb_method_definition_t struct
We only have 12 method types, so 4 bits is enough for rb_method_type_t. Size reductions: - x86-64 48 => 40 bytes - x86 28 => 24 bytes * method.h (enum method_optimized_type): split out for CPP (struct rb_method_definition struct): pack on unaligned systems (rb_method_definition_t): split typedef to help ctags [ruby-core:81236] [Feature #13494] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58784 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
