Subject: New gc_status() fields, and WeakMap cycle collection
From: arnaud.lb@gmail.com (Arnaud Le Blanc)

Hi everyone,

I'm considering merging the following two PRs:

https://github.com/php/php-src/pull/11523: Exposes the time spent in
the cycle collector via new gc_status() fields.
https://github.com/php/php-src/pull/10932: Allows the GC to collect
certain types of cycles involving WeakMaps.

The second one introduces a minor BC break.

If there are no objections, I plan to merge these PRs prior to the
feature freeze.

Best regards,
Arnaud
