http://llvm.org/reports/coverage/ is generated using lcov (on top of 
LLVM's gcov emulation, I think?).  lcov has support for something it 
calls "branch coverage", but it's buggy; when I tried to generate a 
report with it enabled, it hung.

http://lab.llvm.org:8080/coverage/coverage-reports/clang/index.html is 
generated using LLVM source-based code coverage 
(https://clang.llvm.org/docs/SourceBasedCodeCoverage.html). Currently, 
it doesn't have any support for decision coverage.
