Add a new builtin type, an 8-byte integer, and allow GDB to parse 'integer (kind=8)', returning the new 8-byte integer. gdb/ChangeLog: * f-exp.y (convert_to_kind_type): Handle integer (kind=8). * f-lang.c (build_fortran_types): Setup builtin_integer_s8. * f-lang.h (struct builtin_f_type): Add builtin_integer_s8 field. gdb/testsuite/ChangeLog: * gdb.fortran/type-kinds.exp: Test new integer type kind.
