* regparse.c (PINC): use optimized enclen() instead of
ONIGENC_MBC_ENC_LEN(). * regparse.c (PFETCH): ditto. * regparse.c (PFETCH): small optimization. * regexec.c (slow_search): single byte encoding optimization. * regenc.h (enclen): avoid calling function when encoding's min_len == max_len. * re.c (rb_reg_regsub): rb_enc_ascget() optimization for single byte encoding. * re.c (rb_reg_search): avoid allocating new re_registers if we already have MatchData. * re.c (match_init_copy): avoid unnecessary onig_region_free() before onig_region_copy. * encoding.c (rb_enc_get_index): remove implicit enc_capable check each time. * encoding.c (rb_enc_set_index): ditto. * encoding.c (enc_compatible_p): small refactoring. * include/ruby/encoding.h (rb_enc_dummy_p): inline rb_enc_dummy_p() and export related code. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@16477 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
