Keno Fischer 93e3e80c72 [StripDeadDebugInfo] Drop dead CUs entirely ...

Summary:
Prior to this while it would delete the dead DIGlobalVariables, it would
leave dead DICompileUnits and everything referenced therefrom. For a bit
bitcode file with thousands of compile units those dead nodes easily
outnumbered the real ones. Clean that up.
