    • Fix test failure when -fno-inline is used · 6908c1dc 
      This currently checks _GLIBCXX_USE_DUAL_ABI which is incorrect, as that
can be true when _GLIBCXX_USE_CXX11_ABI == 0. The correct check would be
_GLIBCXX_USE_CXX11_ABI == 1, but that's made redundant by the cxx11-abi
effective target that the test requires. However, the test will fail if
-fno-inline is used, so check __NO_INLINE__ instead.

	* testsuite/23_containers/list/61347.cc: Avoid spurious failure when
	-fno-inline added to test flags.

    • Fix bugs in filesystem::path::lexically_normal() · 73d968d9 
      Using path::_List::erase(const_iterator) to remove a non-final component
in path::lexically_normal() is a bug, because it leaves the following
component with an incorrect _M_pos value.

Instead of providing erase members that allow removing components from
the middle, replace them with pop_back() and
_M_erase_from(const_iterator) which only allow removing elements at the
end. Most uses of erase are unaffected, because they only remove
elements from the end anyway. The one use of erasure from the middle in
lexically_normal() is replaced by calls to pop_back() and/or clearing
the last component to leave it as an empty final filename.

Also replace the "???" comment in lexically_normal() to document when
that branch is taken.

	* include/bits/fs_path.h (path::_List::erase): Replace both overloads
	with ...
	(path::pop_back(), path::_M_erase_from(const_iterator)): New member
	functions that will only erase elements at the end.

    • Avoid spurious test failures when -fno-inline in test flags · 5db78cac 
      These tests rely on inlining, so if -fno-inline is added to the compiler
flags the tests fail. Use the predefined __NO_INLINE__ macro to detect
that situation, and don't bother testing the move assignment.

    • x86: relax mask register constraints · 80b23ae8 
      While their use for masking is indeed restricted to %k1...%k7, use as
"normal" insn operands also permits %k0. Remove the unnecessary
limitations, requiring quite a few testsuite adjustments.

Oddly enough some AVX512{F,DQ} test cases already check for %k[0-7],
while others did permit {%k0} - where they get touched here anyway this
gets fixed at the same time.
