Rollup merge of #56059 - alexcrichton:fix-tests, r=sfackler
Increase `Duration` approximate equal threshold to 1us

Previously this threshold when testing was 100ns, but the Windows
documentation states:

> which is a high resolution (<1us) time stamp

which presumably means that we could have up to 1us resolution, which
means that 100ns doesn't capture "equivalent" time intervals due to
various bits of rounding here and there.

It's hoped that this..

Closes #56034

Rollup merge of #56007 - RalfJung:non-const-call, r=oli-obk
CTFE: dynamically make sure we do not call non-const-fn

I'd love to have a test case for this, but I don't know how.

I am also really surprised by this test case that changed behavior: Why did it even start execution if it already determined that it shouldn't?!?

Minor standard library constification

This PR makes some bits of the standard library into `const fn`s.
I've tried to be as aggressive as I possibly could in the constification.
The list is rather small due to how restrictive `const fn` is at the moment.
