We've worked around bugs in the frontend by ignoring the count from wrapped segments when a line has at least one region entry segment. Those frontend bugs are now fixed, so it's time to regenerate the checked-in covmapping files and remove the workaround. llvm-svn: 317761

// Check that llvm-cov loads real coverage mapping data for a function

// even though dummy coverage data for that function comes first.

// Dummy coverage data is exported if the definition of an inline function
|
|
// is seen but the function is not used in the translation unit.

// clang++ -fprofile-instr-generate -fcoverage-mapping -o tmp -x c++ prefer_used_to_unused.h prefer_used_to_unused.cpp
|
