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.

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