This flag turned out to be less useful than anticipated, and interferes with
work towards expansion support.

<title>coverage: Add debugging flag `-Zcoverage-options=no-mir-spans`</title>

<id>urn:sha1:abc2c702af0b7b2eb36fb35839a322f5789af141</id>
<content type='text'>
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.

<id>urn:sha1:5330ccdb345b24be57f051c6659cd3b33a65fdca</id>
<content type='text'>
For PGO/coverage tests that don't need to build or run an actual artifact, we
can use `-Zno-profiler-runtime` to run the test even when the profiler runtime
is not available.
