1) Handling of the DW_AT_byte_size attribute when processing a

DW_TAG_string_type (this is acceptable under the current DWARF 2.1/3.0
standard.)
2) In read_tag_string_type(), a fix for FORTRAN that propagates the
first string length to all string types. This is important as FORTRAN
strings are not delimited as in C/C++.
3) Handling of the DW_LANG_Fortran95.
