lld-link cannot find std::vector destructor in certain situations

[AlexB8675]

using latest clang-cl and lld-link (20.1.8) on Windows 11 24H2 with latest build tools 17.14.9, the following code snippet fails to link

#include <vector>

struct Foo {
  int x;
};

struct Bar {
  std::vector<Foo*> a;
  std::vector<Foo*> b;
};

int main() {
  auto one = Foo(1);

  auto* bar = new Bar(
    { &one },
    { &one }
  );

  return 0;
}

With the following terminal commands

D:\LLVM\bin\clang-cl.exe  /nologo -TP  -IC:\Users\Alex\Desktop\Test\build\_deps\mimalloc-src\include /DWIN32 /D_WINDOWS /EHsc /Ob0 /Od /RTC1 -clang:-std=c++23 -MDd -Zi /MDd /showIncludes /FoCMakeFiles\Test.dir\main.cpp.obj /FdCMakeFiles\Test.dir\ -c -- C:\Users\Alex\Desktop\Test\main.cpp

Workarounds include:

• Not using C++20's parenthesis aggregate init of bar
• Adding delete for bar

Workarounds include:
- Not using C++20's parenthesis aggregate init of `bar`
- Adding `delete` for `bar`
