[clang][clangd] Don't crash/assert on -gsplit-dwarf=single without ou…
6d9fcc2 
…tput

The crash happens in clang::driver::tools::SplitDebugName when Output is
InputInfo::Nothing. It doesn't happen with standalone clang driver because
output is created in Driver::BuildJobsForActionNoCache.

Example backtrace:
```
