compiler/parse_inst_mode_name.m:
When trying to parse an inst or mode name and failing, we used to just
print the whole term (including the correct parts) and a message about
the mode being invalid. We now print a message for each incorrect *part*
of a term, and make its message specific to the particular problem.
Rename the predicates that parse insts and modes to include "parse"
in their names, and make them take the additional arguments needed
for detailed error reporting.
compiler/parse_sym_name.m:
Put the arguments of a utility predicate in a more sensible order.
compiler/add_clause.m:
compiler/parse_class.m:
compiler/parse_inst_mode_defn.m:
compiler/parse_item.m:
compiler/parse_mutable.m:
compiler/parse_pragma.m:
compiler/parse_tree_out.m:
compiler/parse_type_defn.m:
compiler/parse_type_name.m:
compiler/parse_util.m:
compiler/superhomogeneous.m:
Conform to the changes above. Make some minor improvements.
compiler/hlds_out_util.m:
Add a utility predicate for use by the code above.
Avoid throwing an unnecessary exception.
