Previously, callers of pg_newlocale_from_collation() did not call it if the collation was DEFAULT_COLLATION_OID and instead proceeded with a pg_locale_t of 0. Instead, now we call it anyway and have it return 0 if the default collation was passed. It already did this, so we just have to adjust the callers. This simplifies all the call sites and also makes future enhancements easier. After discussion and testing, the previous comment in pg_locale.c about avoiding this for performance reasons may have been mistaken since it was testing a very different patch version way back when.
