Fix problem with ICF where diffs in EH frame info is ignored.
PR gold/21066
* gc.h (gc_process_relocs): Track relocations in .eh_frame sections
when ICF is enabled, even though the .eh_frame sections themselves
are not foldable.
* icf.cc (get_section_contents): Change arguments to permit operation
on just part of a section. Include extra identity regions in the
referring section's contents recursively.
(match_sections): Lock object here instead of in get_section_contents
so that get_section_contents can operate recursively.
(Icf::add_ehframe_links): New method.
(Icf::find_identical_sections): Pass .eh_frame sections to
add_ehframe_links(). Increase default iteration count from 2 to 3
because handling exception info typically requires one extra iteration.
* icf.h (Icf::extra_identity_list_): New data member with accessor.
(is_section_foldable_candidate): Include .gcc_except_table sections.
* options.h: Update documentation for new default ICF iteration count.
* testsuite/Makefile.am (icf_test_pr21066): New test case.
* testsuite/Makefile.in: Regenerate.
* testsuite/icf_test_pr21066.cc: New source file.
* testsuite/icf_test_pr21066.sh: New test script.
