* string.c (rb_str_squeeze_bang): specialized for 7bit characters in
ASCII compatible strings.
* string.c (rb_str_count): ditto.
* string.c (tr_trans): preserve 7bit/valid coderange flag.
* string.c (rb_str_squeeze_bang): preserve previous coderange value.
* string.c (rb_str_lstrip_bang): ditto.
* string.c (rb_str_rstrip_bang): ditto.
* encoding.c (rb_default_external_encoding): preserve
default_external_encoding in a static variable.
* string.c (single_byte_optimizable): check coderange first, to
reduce number of calling rb_enc_from_index().
