Fergus Henderson 270c12e80e Report an error if the first argument of a `some' goal ...

Estimated hours taken: 0.75

Report an error if the first argument of a `some' goal
is not a list of variables.

compiler/prog_io.m:
compiler/prog_io_util.m:
	Move `parse_list_of_vars' from prog_io.m to prog_io_util.m.

compiler/prog_io_goal.m:
	Check to make sure that the first argument to a some
	goal is a list of variables.  (If not, we don't report
	an error here -- the error will be reported by typecheck.m.)

compiler/typecheck.m:
	Report an proper error message if there is a call to an
	undefined predicate `some/2'.
	Also add `some/2' and `all/2' to the list of language builtins
	for which we report a special error message if they occur as
	undefined function symbols.

tests/invalid/Mmakefile:
tests/invalid/some.m:
tests/invalid/some.err_exp:
	Regression test for the above change.
