Instead of extracting raw coverage mappings into an artifact directory, actually generate useful html reports for a given list of binaries with symbol demangling turned on. No tests, but this is actively being used to drive the (still nascent) coverage bot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@275927 91177308-0d34-0410-b5e6-96231b3b80d8
