`m` means `unsigned long` in mangled name (5.1.5.2 Builtin types 
<https://itanium-cxx-abi.github.io/cxx-abi/abi.html#mangling-builtin>), which 
is the `size` of sized deallocation.

  $ c++filt _ZdlPvmSt11align_val_t _ZdlPvm
  operator delete(void*, unsigned long, std::align_val_t)
  operator delete(void*, unsigned long)

I am not familiar  with libcxx, can you please help me to fix these tests? I 
hope we can catch up with the release of LLVM 17.
