This allows us to assume that coverage spans will only be discarded during
codegen in very unusual situations.

4d5a1acebf coverage: Only merge adjacent coverage spans
This also removes some manipulation of the function signature span that only
made sense in the context of merging non-adjacent spans.

577272eede coverage: Shrink call spans to just the function name
This is a way to shrink call spans that doesn't involve mixing different spans,
and avoids overlap with argument spans.

This patch also removes some low-value comments that were causing rustfmt to
ignore the match arms.

ee7dc06cf1 coverage: Store BCB node IDs in mappings, and resolve them in codegen
Even though the coverage graph itself is no longer available during codegen,
its nodes can still be used as opaque IDs.

996bdabc2a coverage: Remove unhelpful code for handling multiple files per function
Functions currently can't have mappings in multiple files, and if that ever
changes (e.g. to properly support expansion regions), this code will need to be
completely overhauled anyway.
