Dodji Seketeli 70d5afdaa2 Compact & intuitive reporting for changed function parameters ...

* include/abg-comparison.h (unsigned_changed_parm_map)
	(unsigned_parm_map): New typedefs.
	* src/abg-comparison.cc
	(function_decl_diff::subtype_changed_parms): Renamed this from
	changed_parms.
	(function_decl_diff::priv::subtype_changed_parms_}): Renamed this
	from changed_parms_;
	(function_decl_diff::priv::{deleted_parms_by_id_,
	added_parms_by_id_, changed_parms_by_id_}): New members.
	(function_decl_diff::ensure_lookup_tables_populated): Update the
	new priv::changed_parms_by_id_ member to contain the parameters
	that got changed, as opposed to the subtype_changed_parms_ member
	that contain parameters that got a sub-type change.  The other
	priv::*_by_id_ members are helpers for this.  Update them too.
	(function_decl_diff::subtype_changed_parms): Renamed this from
	::changed_parms.
	(function_decl_diff::report): Report separately about parameters
	having a sub-type change, and parameters that got changed.  Note
	that in both cases, the change is necessarily to a compatible
	type.
	* data/test-diff-dwarf/test2-v0.cc: New test file.
	* data/test-diff-dwarf/test2-v0.o: Likewise.
	* data/test-diff-dwarf/test2-v1.cc: Likewise.
	* data/test-diff-dwarf/test2-v1.o: Likewise.
	* data/test-diff-dwarf/test2-report.txt: Likewise.
	* tests/Makefile.am: Add the new test files above to the
	distribution.
	* tests/test-diff-dwarf.cc: Consume the input files above to
	actually perform a regression test.
