My understanding is that these API are perma unstable, so it doesn't
make sense to pollute docs & IDE completion[1] with them.

This fixes occasional proptest failures due to a bug in xsv, which
aren't related to bugs in the rust compiler.

Fixes: rust-lang#79725

Some macros can create a situation where `fn_sig_span` and `body_span`
map to different files.

New documentation on coverage tests incorrectly assumed multiple test
binaries could just be listed at the end of the `llvm-cov` command,
but it turns out each binary needs a `--object` prefix.

This PR fixes the bug and updates the documentation to correct that
issue. It also fixes a few other minor issues in internal implementation
comments, and adds documentation on getting coverage results for doc
tests.

Using an `if` seems like a better semantic fit and saves a few lines.

When encoding a proc-macro crate, there may be gaps in the table (since
we only encode the crate root and proc-macro items). Account for this by
checking if the entry is present, rather than using `unwrap()`

minor stylistic clippy cleanups

simplify if let Some(_) = x  to  if x.is_some()  (clippy::redundant_pattern_matching)
don't create owned values for comparison (clippy::cmp_owned)
use .contains() or .any() instead of find(x).is_some() (clippy::search_is_some)
don't wrap code block in Ok()  (clipppy::unit_arg)

Update xsv to prevent random CI failures

aren't related to bugs in the rust compiler.
