git_commit commit 4884d6cbce99286e349e239c1c1103b9f3820b56

[libc++] Extend __default_three_way_comparator to any types that only implements operator<=> (#157602)

This uses the new `__builtin_lt_synthesises_from_spaceship` builtin from
clang to use three way comparison for arbitrary user-defined types that
only provide a spaceship operator.
