libstdc++: Use std::string::__resize_and_overwrite in std::filesystem
There are a few places in the std::filesystem code that use a string as
a buffer for OS APIs to write to. We can use the new extension
__resize_and_overwrite to avoid redundant initialization of those
buffers.
libstdc++-v3/ChangeLog:
* src/c++17/fs_ops.cc (fs::absolute) [FILESYSTEM_IS_WINDOWS]:
Use __resize_and_overwrite to fill buffer.
(fs::read_symlink) [HAVE_READLINK]: Likewise.
* src/filesystem/ops-common.h (get_temp_directory_from_env)
[FILESYSTEM_IS_WINDOWS]: Likewise.
