Selective scheduling and its usage

[Martin Liška]

Hello.

I noticed there are quite many selective scheduling PRs:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84872
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84842
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84659

and many others.

I want to ask you if you plan to maintain the scheduling?
Is it enabled by default for any target we support?
Should we deprecate it for GCC 8?

Thank you,
Martin
