Using an enum here was historically not worth the extra hassle, but now we can
lean on `#[derive(TryFromU32)]` to hide most of the boilerplate.
coverage: Infer `instances_used` from `pgo_func_name_var_map`2025-07-27T11:49:37+00:00ZalatharZalathar@users.noreply.github.com2025-07-27T11:19:07+00:00urn:sha1:24e2b4832bfa0bf1b60159af0ae11b15de55590e
In obscure circumstances, we would sometimes emit a covfun record for a
function with no physical coverage counters, causing `llvm-cov` to fail with
the cryptic error message:
malformed instrumentation profile data: function name is empty
We can eliminate this mismatch by removing `instances_used` entirely, and
instead inferring its contents from the keys of `pgo_func_name_var_map`.
This makes it impossible for a "used" function to lack a PGO name entry.
