Message:

Formatting: Improve performance of wpautop() on large paragraphs.

Following [45585], older versions of PHP could segfault when attempting to autop paragraphs with 10,000+ characters.

Rather than having to negative lookahead for every character in the paragraph (which could run into recursion limits), we can quickly jump ahead to the next tag and start checking from there.

See #27350.
