Davide Italiano d7b0922d20 [opt] Strip coverage if debug info is not present. ... If -coverage is passed, but -g is not, clang populates the PassManager pipeline with StripSymbols(debugOnly = true). The stripSymbol pass therefore scans the list of named metadata, drops !llvm.dbg.cu, but leaves !llvm.gcov and !0 (the compileUnit MD) around. The verifier runs, and finds out that there's a CU not listed in !llvm.dbg.cu (as it was previously dropped) -> crash. When we strip debug info, so, check if there's coverage data, and strip it as well, in order to avoid pending metadata left around.
