Added better warnings and error messages. Fixed bug with having
pragma(c_code, ...) decs for different modes of the same pred, and with having
clauses and pragma(c_code, ...) decs.

hlds.m:
	Added a fields to the pred_info indicating whether the pred contained
	pragma(c_code, ...) decs, clauses, or was currently empty. Also
	updated the access predicates, and require a new argument for
	pred_info_init
lambda.m:
	Pass the new argument to pred_info_init
make_hlds.m:
	Improve error messages and warnings. Fix bug with pragma decs for
	different modes, and bug with clauses an pragmas for same pred.
