Message:

General: Backport polyfills for str_ends_with() and str_starts_with().

Uses src/wp-includes/functions.php becouse commiting to src/wp-includes/compat.php fails due to the presence of __autoload.

Merges [52040], [56016], and [56015] to 4.6 branch.

Props ocean90, SergeyBiryukov, desrosj, joemcgill, jorbin, mukesh27.
