Zalathar 86a66c8171 coverage: Store each BCB's code regions in one coverage statement 
If a BCB has more than one code region, those extra regions can now all be
stored in the same coverage statement, instead of being stored in additional
statements.

README.md

The tests in ./status-quo were copied from tests/run-coverage in order to capture the current behavior of the instrumentor on non-trivial programs. The actual mappings have not been closely inspected.

Maintenance note

These tests can be sensitive to small changes in MIR spans or MIR control flow, especially in HIR-to-MIR lowering or MIR optimizations.

If you haven't touched the coverage code directly, and the run-coverage test suite still works, then it should usually be OK to just --bless these coverage mapping tests as necessary, without worrying too much about the exact changes.
