encoding.h: ENC_CODERANGE_CLEAN_P
* include/ruby/encoding.h (ENC_CODERANGE_CLEAN_P): predicate that
tells if the coderange is clean, that is 7bit or valid, and no
needs to scrub.
* re.c (rb_reg_expr_str): use ENC_CODERANGE_CLEAN_P.
* string.c (enc_strlen, rb_enc_cr_str_buf_cat, rb_str_scrub):
ditto.
* string.c (rb_str_enumerate_chars): ditto, and suppress a warning
by gcc6.
