Jonathan Wakely cda121ac7a PR libstdc++/83328 add correct basic_string::insert for initializer_list 
The SSO basic_string has a non-standard insert(iterator, initializer_list)
overload, from a C++0x draft. This adds the correct overload, while also
preserving the old one so that the old symbol is still exported from the
library.

The COW basic_string doesn't have any of the C++11 changes to the insert
overloads (they all still have non-const iterator parameters and the
ones that should return an iterator still return void). This doesn't
make any change to the COW string.

Jonathan Wakely b02923592a Add support for opening file streams from wide character strings 
C++17 added new overloads to <fstream> class templates to support
opening files from wide character strings "on systems where
filesystem::path::value_type is not char". This patch adds those
overloads conditional on _wfopen being available, and enables them for
pre-C++17 modes as well.

Kyrylo Tkachov 0e0cefc62e [aarch64][libstdc++] Use __ARM_BIG_ENDIAN instead of __AARCH64EB__ in opt_random.h 
As has been spotted at https://gcc.gnu.org/ml/gcc-patches/2017-12/msg01289.html
we check the __AARCH64EB__ macro for aarch64 big-endian
detection in config/cpu/aarch64/opt/ext/opt_random.h.
That works just fine with GCC but the standardised ACLE[1] macro
for that purpose is __ARM_BIG_ENDIAN so there is a possibility
that non-GCC compilers that include this header are not aware
of this predefine.

So this patch changes the use of __AARCH64EB__ to
the more portable __ARM_BIG_ENDIAN.

Tested on aarch64-none-elf and aarch64_be-none-elf.

Preapproved by Jeff at https://gcc.gnu.org/ml/gcc-patches/2017-12/msg01326.html

	* config/cpu/aarch64/opt/ext/opt_random.h (__VEXT): Check
	__ARM_BIG_ENDIAN instead of __AARCH64EB__.
