rename absolute_path to realpath internally and introduce pathobj. * vm_core.h: rename absolute_path to realpath because it is expected name. external APIs (#absolute_path methods) are remained. * vm_core.h: remove rb_iseq_location_struct::path and rb_iseq_location_struct::absolute_path and introduce pathobj. if given path equals to given absolute_path (and most of case it is true), pathobj is simply given path String. If it is not same, pathobj is Array and pathobj[0] is path and pathobj[1] is realpath. This size optimization reduce 8 bytes and sizeof(struct rb_iseq_constant_body) is 200 bytes -> 192 bytes on 64bit CPU. To support this change, the following functions are introduced: * pathobj_path() (defined in vm_core.h) * pathobj_realpath() (ditto) * rb_iseq_path() (decl. in vm_core.h) * rb_iseq_realpath() (ditto) * rb_iseq_pathobj_new() (ditto) * rb_iseq_pathobj_set() (ditto) * vm_core.h (rb_binding_t): use pathobj instead of path. If binding is given at eval methods, realpath (absolute_path) was caller's realpath. However, they should use binding's realpath. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58979 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
