Zoltan Somogyi bc56e927b6 Detect when a predicate has a pair of I/O states but isn't det or cc_multi.

Estimated hours taken: 6
Branches: main

Detect when a predicate has a pair of I/O states but isn't det or cc_multi.
Improve the generation of determinism error messages.

compiler/det_analysis.m:
	Detect when a predicate has a pair of I/O states but isn't det or
	cc_multi.

	Factor out some common code.

compiler/det_report.m:
	Add the new error type for predicates with I/O states.

	Use error_util much more extensively to generate error messages.

compiler/hlds_out.m:
	For several existing predicates that write out various HLDS
	constructs, provide versions that return representations of those
	constructs as strings or as error_util pieces, for use by det_report.m.
	Redefine the old predicates as simply printing the output of the new
	predicates where relevant, to avoid code duplication.

compiler/error_util.m:
	When describing a predicate name, specify whether we want to module
	qualify the name or not. The intention is that when generating a kind
	of error message which can only be generated for predicates defined
	in the current module, the module prefix should be omitted in the
	interest of clarity.

compiler/accumulator.m:
compiler/dead_proc_elim.m:
compiler/magic_util.m:
compiler/table_gen.m:
compiler/term_errors.m:
compiler/termination.m:
compiler/typecheck.m:
	Conform to the changes in error_util.m.

compiler/globals.m:
	Reorder arguments to allow the use of state variable notation.

compiler/handle_globals.m:
compiler/mercury_compile.m:
compiler/source_file_map.m:
	Conform to the changed argument order in globals.m.
