[clang] [CIR][NFC] Remove dead member function from EHScopeStack::Cleanup (PR #162565)

[Andy Kaylor via cfe-commits]

https://github.com/andykaylor created https://github.com/llvm/llvm-project/pull/162565

This removes the `getSize()` member function from EHScopeStack::Cleanup and all its subclasses. This function had originally been added as a temporary measure before EHCleanupScope was implemented, but it is no longer used.

Subject: [PATCH] [CIR][NFC] Remove dead member function from
 EHScopeStack::Cleanup

This removes the `getSize()` member function from EHScopeStack::Cleanup
and all its subclasses. This function had originally been added as a
temporary measure before EHCleanupScope was implemented, but it is no
longer used.
