PR libstdc++/90634 reduce allocations in filesystem::path construction
PR libstdc++/90634
* include/experimental/bits/fs_path.h (path::path(path&&)): Only call
_M_split_cmpts() for a path with multiple components.
(path::_S_is_dir_sep()): Add missing 'static' keyword to function.
* src/filesystem/path.cc (path::_M_split_cmpts()): Count number of
components and reserve space in vector. Return early when there is
only one component.
* testsuite/27_io/filesystem/path/construct/90634.cc: New test.
* testsuite/experimental/filesystem/path/construct/90634.cc: New test.
