H.J. Lu 59fa66c538 Handle symbol defined in IR and referenced in DSO 
We need to make an IR symbol visible if it is defined in an IR object
and referenced in a dynamic object.  When --as-needed is used, since
linker removes the IR symbol reference of the dynamic object if the
dynamic object isn't needed in the first pass, the IR definition isn't
visible to the dynamic object even if the dynamic object becomes needed
in the second pass.  Add dynamic_ref_after_ir_def to bfd_link_hash_entry
to track IR symbol which is defined in an IR object and later referenced
in a dynamic object.  dynamic_ref_after_ir_def is preserved when restoring
the symbol table for unneeded dynamic object.

bfd/

	PR ld/21382
	* elflink.c (elf_link_add_object_symbols): Preserve
	dynamic_ref_after_ir_def when restoring the symbol table for
	unneeded dynamic object.

include/

	PR ld/21382
	* bfdlink.h (bfd_link_hash_entry): Add dynamic_ref_after_ir_def.

ld/

	PR ld/21382
	* plugin.c (is_visible_from_outside): Symbol may be visible
	from outside if dynamic_ref_after_ir_def is set.
	(plugin_notice): Set dynamic_ref_after_ir_def if the symbol is
	defined in an IR object and referenced in a dynamic object.
	* testsuite/ld-plugin/lto.exp: Run PR ld/21382 tests.
	* testsuite/ld-plugin/pr21382a.c: New file.
	* testsuite/ld-plugin/pr21382b.c: Likewise.
