	* 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.

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.

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.

	Implement P2092R0, Disambiguating Nested-Requirements

	CP_PARSER_FLAGS_TYPENAME_OPTIONAL.

We were enabling the memcmp optimization in ranges::lexicographical_compare for
signed integral types and for integral types wider than a byte.  But memcmp
gives the wrong answer for arrays of such types.  This patch fixes this issue by
refining the condition that enables the memcmp optimization.  It's now
consistent with the corresponding condition used in
std::lexicographical_compare.

libstdc++-v3/ChangeLog:

	PR libstdc++/93972
	* include/bits/ranges_algo.h (__lexicographical_compare_fn::operator()):
	Fix condition for when to use memcmp, making it consistent with the
	corresponding condition used in std::lexicographical_compare.
	* testsuite/25_algorithms/lexicographical_compare/93972.cc: New test.

The awaitable initially committed was returning "always ready"
which meant that the suspension code was not used.  Update
the test to suspend at each co_await, since this exercises more
of the infrastructure.
