[PATCH] D70571: [Coverage] Emit a gap region to cover switch bodies

vsk edited the summary of this revision.

Emit a gap region beginning where the switch body begins. This sets line
execution counts in the areas between non-overlapping cases to 0.

This does not resolve an outstanding issue with case statement regions
that do not end when a region is terminated. But it should address
llvm.org/PR44011.
