Rollup merge of #115300 - spastorino:smir-tweaks, r=oli-obk 
Tweaks and improvements on SMIR around generics_of and predicates_of

r? `@oli-obk`

This allows an API like the following ...

```rust
    let trait_decls = stable_mir::all_trait_decls().iter().map(|trait_def| {
        let trait_decl = stable_mir::trait_decl(trait_def);
        let generics = trait_decl.generics_of();
        let predicates = trait_decl.predicates_of().predicates;
```

I didn't like that much `trait_def.trait_decl()` which is it possible but adding a method to a def_id that loads up a whole trait definition looks backwards to me.

c5035271ac Auto merge of #115211 - spastorino:add-missing-smir-generics-of, r=compiler-errors 
Add missing high-level stable_mir::generics_of fn

We forgot to add this function in https://github.com/rust-lang/rust/pull/115092, as we have done on https://github.com/rust-lang/rust/pull/115084 and other high level APIs.

At some point I think we should re-organize the structure of the code but this is what we have for now.

Add stable for Constant in smir

Previously https://github.com/rust-lang/rust/pull/114587 we covered much of the groundwork needed to cover Const in smir, so there is no reason keep `Constant` as String.

Treat `StatementKind::Coverage` as completely opaque for SMIR purposes

Coverage statements in MIR are heavily tied to internal details of the coverage implementation that are likely to change, and are unlikely to be useful to third-party tools for the foreseeable future.

With this, the output on double-panic becomes something like that:

thread caused non-unwinding panic. aborting.
```
If we also land https://github.com/rust-lang/rust/pull/115020, the 2nd backtrace disappears, hopefully making the "panic in a destructor during cleanup" easier to see.

Fixes https://github.com/rust-lang/rust/issues/114954.

1fac8a0eab Treat StatementKind::Coverage as completely opaque for SMIR purposes 
Coverage statements in MIR are heavily tied to internal details of the coverage
implementation that are likely to change, and are unlikely to be useful to
third-party tools for the foreseeable future.

d88ab223c5 fix: add RiscvInterrupt* cconv to smir 
These new interrupt calling conventions are not themselves stabilized,
but there are other unstable calling conventions present in the SMIR
mapping (e.g. AVR interrupts) and the mapping appears to be "complete"
so far, with no obvious way to represent unstable conventions separately
from the stable ones.
