Kiran's Add last_full_sweep to GC stats #18

Just to save us time I opened a PR with Kiran's patch to Julia 1.8.2-RAI so we can use this patch is master.

Whenever the GC runs a full sweep, it records the time_ns() at which the full sweep completed in GC_Num.
This should be replaced by backporting the upstream PR, when we open that.

There's already this, which I will update and merge today along with our RAI Julia build (which is v1.8.2+RAI and in the future v1.9.1+RAI; will clean up old branch names from this repo). So this can be closed.

`@something` eagerly unwraps any `Some` given to it, while keeping the
variable between its arguments the same. This can be an issue if a
previously unpacked value is used as input to `@something`, leading to a
type instability on more than two arguments (e.g. because of a fallback
to `Some(nothing)`). By using different variables for each argument,
type inference has an easier time handling these cases that are isolated
to single branches anyway.

This also adds some comments to the macro, since it's non-obvious what
it does.

Benchmarking the specific case I encountered this in led to a ~2x
performance improvement on multiple machines.
