Hi I noticed an error in clang-13 code coverage reporting.
If you follow these steps:
```
clang test.c -fprofile-instr-generate -fcoverage-mapping -g -O0 -DDEBUG -o test
./test
llvm-profdata merge -sparse ./default.profraw -o ./test.profdata
llvm-cov show ./test -instr-profile=./test.profdata
```
The resulting coverage report is:
```
1| |#include <assert.h>
2| |#include <stdio.h>
3| |
4| 1|int main() {
5| 1| assert(1);
6| 0| puts("not covered"); // line after assert is not covered
7| 1| puts("covered");
8| 1| assert(1);
9| 0| puts("not covered"); // line after assert is not covered
10| 1| assert(1);
11| 0| assert(1); // line after assert is not covered
12| 0| puts("not covered"); // line after assert is not covered
13| 1|}
```
as you can see all lines after an `assert(...)` are ignored, this is a
regression as clang-12 doesn't have this behaviour</pre>
