coverage: Detect unused local file IDs to avoid an LLVM assertion
...
This case can't actually happen yet (other than via a testing flag), because
currently all of a function's spans must belong to the same file and expansion.
But this will be an important edge case when adding expansion region support.

coverage: Hoist counter_for_bcb out of its loop

Having this helper function in the loop was confusing, because it doesn't rely
on anything that changes between loop iterations.

coverage: Enlarge empty spans during MIR instrumentation, not codegen

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

coverage: Convert and check span coordinates without a local file ID
...
For expansion region support, we will want to be able to convert and check
spans before creating a corresponding local file ID.
If we create local file IDs eagerly, but some expansion turns out to have no
successfully-converted spans, LLVM will complain about that expansion's file ID
having no regions.

coverage: Add LLVM plumbing for expansion regions

regions without having to worry about the FFI parts.

coverage: Don't refer to the body span when enlarging empty spans
...
Given that we now only enlarge empty spans to "{" or "}", there shouldn't be
any danger of enlarging beyond a function body.

coverage: Make query coverage_ids_info return an Option
...
This reflects the fact that we can't compute meaningful info for a function
that wasn't instrumented and therefore doesn't have `function_coverage_info`.

coverage: Quietly skip functions that end up having no mappings
...
In codegen, a used function with `FunctionCoverageInfo` but no mappings has
historically indicated a bug. However, that will no longer be the case after
moving some fallible span-processing steps into codegen.
