When generating the separate file with LTO debug sections, we should
also copy .note.gnu.property section.

	PR lto/93966
	* simple-object.c (handle_lto_debug_sections): Also copy
	.note.gnu.property section.

	* lto-wrapper.c: Fix typo in comment about
	C++ standard version.

Several scev/IVOPTs cases aim to check some array references are sceved and
later marked as REFERENCE ADDRESS IV groups. With IV group type dumping
improving, these check strings can be improved. Otherwise, they become fragile
with dumping changes.

This patch is to keep check strings concise, meanwhile recover the coverage of
case scev-8.c.

	* g++.dg/coroutines/torture/class-07-data-member.C: New test.

The current imported libsanitizer code produces kernel panics for
Darwin 11 (macOS 10.7) and is unsupported for earlier versions already.

It is not clear if the current sources are even intended to be supported
on Darwin 11, so this patch causes the default to be build without
sanitizers for Darwin <= 11.

2020-03-01  Iain Sandoe  <iain@sandoe.co.uk>

	PR sanitizer/93731
	* configure.tgt (x86_64-*-darwin*, i?86-*-darwin*): Enable by
	default only for Darwin versions greater than 12 (macOS 10.8).

Darwin10 is no longer supported upstream and will not build without
additional patches.

	* config/abi/post/x86_64-linux-gnu/x32/baseline_symbols.txt: Updated.

The rule change in the title matches GCC's current behavior, so no change
was needed.  But the paper also makes 'typename' optional in a
requirement-parameter-list, so this implements that.
