[ASTImporter] Fix bug introduced in
2ba4e3a4598b
2ba4e3a4598b (Move FPFeatures from BinaryOperator bitfields to Trailing
storage, D76384) introduced an assertion failure during CTU analysis.
The reason is that in ASTNodeImporter::VisitCompoundAssignOperator the
LHSType and the ResultType have been imported twice.
Details:
clang: ../../git/llvm-project/clang/lib/Basic/SourceManager.cpp:918: clang::FileID clang::SourceManager::getFileIDLoaded(unsigned int) const: Assertion `0 && "Invalid SLocOffset or bad function choice"' failed.
