Subject: [DebugInfo] Fix use-after-move warning. NFCI.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=2057585852ce6689e509871903d5cd8ab2c28eb3;p=llvm

[DebugInfo] Fix use-after-move warning. NFCI.

Don't rely on DWARFAbbreviationDeclarationSet::extract cleaning the struct up for reuse - the analyzers don't like it.
