Finding operator delete[] is still problematic, without it the extension is a security hazard, so reverting until the problem with operator delete[] is figured out. This reverts the following PRs: Reland [MS][clang] Add support for vector deleting destructors (llvm#133451) [MS][clang] Make sure vector deleting dtor calls correct operator delete (llvm#133950) [MS][clang] Fix crash on deletion of array of pointers (llvm#134088) [clang] Do not diagnose unused deleted operator delete[] (llvm#134357) [MS][clang] Error about ambiguous operator delete[] only when required (llvm#135041)
