Follow-up to #81037. ToolChain::LibraryPaths holds the new compiler-rt library directory (e.g. `/tmp/Debug/lib/clang/19/lib/x86_64-unknown-linux-gnu`). However, it might be empty when the directory does not exist (due to the `if (getVFS().exists(P))` change in https://reviews.llvm.org/D158475). If neither the old/new compiler-rt library directories exists, we would suggest the undesired old compiler-rt file name: ``` % /tmp/Debug/bin/clang++ a.cc -fsanitize=memory -o a ld.lld: error: cannot open /tmp/Debug/lib/clang/19/lib/linux/libclang_rt.msan-x86_64.a: No such file or directory clang++: error: linker command failed with exit code 1 (use -v to see invocation) ``` With this change, we will correctly suggest the new compiler-rt file name.
