Tyson Dowd 2a97f96d1a Generate stack layouts for accurate garbage collection.
Estimated hours taken: 50

Generate stack layouts for accurate garbage collection.

compiler/base_type_layout.m:
	Change the order of some arguments so that threaded data
	structures are more often in the final two arguments (allows
	easy use of higher order predicates).
	Simplify some code using higher order preds.
	Export base_type_layout__construct_pseudo_type_info, as
	stack_layout.m needs to be able to generate pseudo_type_infos
	too.
	Fix problems with cell numbers being re-used -- get the next
	cell number from module_info, and update module_info
	after processing base_type_layouts.

compiler/code_gen.m:
	Add information about each procedure to the continuation info.
	Handle new field in c_procedure.

compiler/continuation_info.m:
	Redesign most of this module to deal with labels
	that are continuation points for multiple calls.
	Change the order of some arguments so that threaded data
	structures are in the final two arguments.
	Cleaned up and documented code.

compiler/dupelim.m:
compiler/exprn_aux.m:
	Handle new label_entry data type.

compiler/export.m:
compiler/opt_debug.m:
	Handle new label_entry and general data types.

compiler/llds_out.m:
	Add an argument to get_proc_label to control whether a
	"mercury_" prefix is wanted.
	Handle new label_entry and general data types.

compiler/llds.m:
	Add a new alternative for data_const - a label_entry.
	Add a new alternative for data_name - general, which
	allows any sort of data, with names generated elsewhere.
	Add the pred_proc_id as a field of c_procedure.

compiler/optimize.m:
compiler/llds_common.m:
compiler/optimize.m:
	Handle new field in c_procedure.

compiler/mercury_compile.m:
	Generate layout information after code has been generated,
	and output stack layouts.

compiler/notes/compiler_design.html:
	Document new stack_layout module.

compiler/stack_layout.m:
	New file - generates the LLDS code that defines
	global constants to hold the stack_layout structures.

compiler/options.m:
compiler/handle_options.m:
	Add --stack-layout option which outputs stack layouts.
	Make accurate gc imply stack_layout.
