coverage: Add debugging flag `-Zcoverage-options=no-mir-spans`
When set, this flag skips the code that normally extracts coverage spans from MIR statements and terminators. That sometimes makes it easier to debug branch coverage and MC/DC coverage, because the coverage output is less noisy. For internal debugging only. If other code changes would make it hard to keep supporting this flag, remove it.
