AsmPrinter: Stop storing MDLocalVariable in DebugLocEntry

Browse Source 
Stop storing the `MDLocalVariable` in the `DebugLocEntry::Value`s.  We
generate the list of `DebugLocEntry`s separately for each
variable/inlined-at pair, so the variable never actually changes here.

This is effectively NFC (aside from saving some memory and CPU time).
