    • libphobos: Fix linker warning and SEGV in core.thread tests. · 2493e718 
      The monolithic core/threadasm.S source has been removed, and split into
multiple parts, one for each intended target CPU/OS.

Added .type and .size directives for all asm implementations of
fiber_switchContent and callWithStackShell where they were missing.

    • Fix basic_string_view typedefs and enforce preconditions · fb8b3e29 
      The basic_string_view::pointer and basic_string_view::reference typedefs
are supposed to refer to the non-const value type.

In previous standards having traits_type::char_type different to
value_type was simply undefined, but in the C++2a draft it's ill-formed,
as changed by P1148R0. For std::basic_string and iostreams we might
want to only enforce this conditionally for __cplusplus > 201703L but
for std::basic_string_view we don't have backwards compatibility
concerns. Also add assertions to verify the _CharT argument is a
"char-like" type (non-array, trivial, standard layout type).

Also remove the non-standard basic_string_view::_M_check and
basic_string_view::_M_limit member functions, replacing them with
non-member functions that will still exist even if basic_string_view is
specialized by the program.

	* include/experimental/string_view (basic_string_view::pointer)
	(basic_string_view::reference): Fix to refer to non-const value_type.
	* include/bits/basic_string.h (basic_string): Use __sv_check and
	__sv_limit instead of basic_string_view::_M_check and

	* include/std/string_view (__sv_check, __sv_limit): New
	helper functions to replace basic_string_view::_M_check and
	basic_string_view::_M_limit.
	(basic_string_view): Add static assertions to enforce ill-formed
	requirement for traits_type::char_type from P1148R0, and to enforce
	required properties of char-like types.

    • PR libstdc++/90220 Fix std::any_cast for array types · 92750002 
      Although the std::any constructors use decay_t to determine the type of
the contained value, std::any_cast should use the un-decayed type (and
so always fail for function and array types that decay to pointers).

Using remove_cv_t is correct, because the condition for std::any_cast
to return non-null is operand.type() == typeid(T) and typeid ignores
top-level cv-qualifiers.

	PR libstdc++/90220
	* include/std/any (__any_caster): Use remove_cv_t instead of decay_t.
	Avoid a runtime check for types that can never be stored in std::any.

    • S/390: Fix PR89952 incorrect CFI · 9fe19400 
      This patch fixes a cases where inconsistent CFI is generated.

After restoring the hard frame pointer (r11) from an FPR we have to
set the CFA register.  In order to be able to set it back to the stack
pointer (r15) we have to make sure that r15 has been restored already.

The patch also adds a scheduler dependency to prevent the instruction
scheduler from swapping the r11 and r15 restore again.
