Add tracing to resolve-related functions
Resolve-related functions are not called often but still make up for ~3% of execution time for non-repetitive programs (as seen in the first table below, obtained from running the rust snippet at the bottom with `n=1`). On the other hand, for repetitive programs they become less relevant (I tested the same snippet but with `n=100` and got ~1.5%), and it appears that only `try_resolve` is called more often (see the last two tables).
The first table was obtained by opening the trace file in https://ui.perfetto.dev and running the following query:
```sql
select "TOTAL PROGRAM DURATION" as name, count(*), max(ts + dur) as "sum(dur)", 100.0 as "%", null as "min(dur)", null as "max(dur)", null as "avg(dur)", null as "stddev(dur)" from slices union select "TOTAL OVER ALL SPANS (excluding events)" as name, count(*), sum(dur), cast(cast(sum(dur) as float) / (select max(ts + dur) from slices) * 1000 as int) / 10.0 as "%", min(dur), max(dur), cast(avg(dur) as int) as "avg(dur)", cast(sqrt(avg(dur*dur)-avg(dur)*avg(dur)) as int) as "stddev(dur)" from slices where parent_id is null and name != "frame" and name != "step" and dur > 0 union select name, count(*), sum(dur), cast(cast(sum(dur) as float) / (select max(ts + dur) from slices) * 1000 as int) / 10.0 as "%", min(dur), max(dur), cast(avg(dur) as int) as "avg(dur)", cast(sqrt(avg(dur*dur)-avg(dur)*avg(dur)) as int) as "stddev(dur)" from slices where parent_id is null and name != "frame" and name != "step" group by name order by sum(dur) desc, count(*) desc
```

The following two tables show how many `resolve` spans there per subname/subcategory, and how much time is spent in each. The first is for `n=1` and the second for `n=100`. The query that was used is:
```sql
select args.string_value as name, count(*), max(dur), avg(dur), sum(dur) from slices inner join args USING (arg_set_id) where args.key = "args." || slices.name and name = "resolve" group by args.string_value
```

The snippet I tested with Miri to obtain the above traces is:
```rust
fn main() {
let n: usize = std::env::args().nth(1).unwrap().parse().unwrap();
let mut v = (0..n).into_iter().collect::<Vec<_>>();
for i in &mut v {
*i += 1;
}
}
```
