string.c: use predefined IDs for minor bloat reduction
* string.c (id_to_s): remove redundant variable (rb_obj_as_string): trade id_to_s for idTo_s (rb_str_equal): replace rb_intern(...) with pre-defined ID (rb_str_cmp_m): ditto (rb_str_match): ditto (str_upto_each): ditto (rb_str_sum): ditto (Init_String): remove id_to_s initialization This leads to a minor size reduction on my x86 (32-bit) system: text data bss dec hex filename 129373 8 32 129413 1f985 string.o-orig 129082 8 8 129098 1f84a string.o git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@52479 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
