Replace wc -l with count

[• rafael]

Summary

This is a far more common way in llvm of counting lines in tests

[rnk]

lgtm This just looks like someone knew more about shell than LLVM testing utilities. :)

11

Maybe make this count 1 < main.txt and save a process?

 // Test for "sancov.py missing ...".
 
 // First case: coverage from executable. main() is called on every code path.
