    strip: Add GCC LTO IR support

"strip --strip-debug" no longer strips debug sections in fat IR objects
since fat IR objects are recognized as plugin object and copied as unknown
objects.  Add a is_strip_input field to bfd to indicate called from strip.
Update bfd_check_format_matches not to treat archive member nor standalone
fat IR object as IR object so that strip can remove debug and IR sections
in fat IR object.  For archive member, it is copied as an unknown object
if the plugin target is in use or it is a slim IR object.  For standalone
fat IR object, it is copied as non-IR object.

	* format.c (bfd_set_lto_type): If there is .llvm.lto section,
	set LTO type to lto_fat_ir_object.
	(bfd_check_format_matches): Don't set LTO type when setting
	format.  When called from strip, don't treat archive member nor
	standalone fat IR object as an IR object.
