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.

Rollup merge of rust-lang#126587 - Zalathar:no-mir-spans, r=oli-obk 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 instrumentation, because the coverage output is less noisy. For internal debugging only. If future code changes would make it hard to keep supporting this flag, it should be removed at that time. `@rustbot` label +A-code-coverage
