Leave lld on beta a little bit more

[lqd]

r? @Kobzol

As discussed, this leaves lld on beta a bit more, to allow for a longer period of testing:

• beta isn't used for testing all that much
• it's summer for the northern hemisphere, activity is low, people are on vacation rather than testing the linker on beta
• we'll advertise this for a longer call for testing on blog.rlo (as soon as I finish the blog post)

(opening as draft as I wonder what tests we can make CI do to check the combination of tests.)

Oh, so we should drop 1.90 release notes + blog mentioning this? We hadn't found much else to talk about in 1.90, so will need to do some digging...

Do we really expect any meaningful feedback within the next 6 weeks from it being on beta? I have doubts that this will really have that effect, but I'll leave it to you to have the final call of course.
Have we gotten any feedback about LLD in the last few months? Statically, nightly gets a lot more testing from people than beta.

I forgot to mention something: I'm not up-to-date on the discussion about the used(linker) changes and their impact (on RfL?), and the current nostart-stop-gc handling (or the lack thereof) relies on it to make linkme work.

Do we really expect any meaningful feedback within the next 6 weeks from it being on beta?

I'm not sure. Maybe not as-is, but with a dedicated blog post motivating people to test their stuff on beta?

On Ferrocene, we actually require folks to use rust-lld and have not experienced problems with LLD. We recently noticed some of our past releases were impacted by the previous change which limited lld to non-stable which requires us to notify our users how to workaround it. We were excited by #140525 since it meant we didn't have to carry a patch for this.

I'm using nightly for running tests in the project just to use lld. It speeds up things for me. For the past 5 months, I have not seen any problems with it.
