Vedant Kumar ee981c0e05 [Coverage] Build sorted and unique segments ... A coverage segment contains a starting line and column, an execution count, and some other metadata. Clients of the coverage library use segments to prepare line-oriented reports. Users of the coverage library depend on segments being unique and sorted in source order. Currently this is not guaranteed (this is why the clang change which introduced deferred regions was reverted). This commit documents the "unique and sorted" condition and asserts that it holds. It also fixes the SegmentBuilder so that it produces correct output in some edge cases. Testing: I've added unit tests for some edge cases. I've also checked that the new SegmentBuilder implementation is fully covered. Apart from running check-profile and the llvm-cov tests, I've successfully used a stage1 llvm-cov to prepare a coverage report for an instrumented clang binary.
