Branch: main
Estimated hours: 24

Add an analysis which determines the set of modules which
are imported but are not used.
It also has a more precise analysis of those modules not needed
in the interface, as it reports more modules than the current
analysis.

compiler/unused_imports.m:
	The module which does the analysis.

compiler/make_hlds_passes.m:
	Record the parent used modules.
	Factor out the code for adding the module specifiers.

compiler/hlds_module.m:
	Add utility predicates for recording those modules
	used in the parent modules of the current module and
	those imports which are in the interface.

compiler/options.m:
	Add the option --warn-unused-imports.
	By default it's turned off because I have yet
	to run this analysis on the compiler and fix
	the modules.

compiler/check_hlds.m:
compiler/mercury_compile.m:
	Add the analysis to the compiler.

doc/user_guide.texi:
	Document the new option.

compiler/notes/compiler_design.html:
	Document the new pass.
