llvm#101920) This fixes regressions caused by llvm#97526 After that patch, all undefined references to DS symbol are removed. This makes DS symbols(for template functions) have no reference in some cases. So extract_symbols.py does not export these DS symbols for these cases. On AIX, exporting the function descriptor depends on references to the function descriptor itself and the function entry symbol. Without this fix, on AIX, we get: ``` rtld: 0712-001 Symbol _ZN4llvm15SmallVectorBaseIjE13mallocForGrowEPvmmRm was referenced from module llvm-project/build/unittests/Passes/Plugins/TestPlugin.so(), but a runtime definition of the symbol was not found. ``` (cherry picked from commit 396343f)
