[Clang] Fix strict weak ordering in ItaniumVTableBuilder
In sorting elements can compare with themselves and sometimes assert further down the line was triggered. The changes are somewhat NFC, which explains the lack of test coverage. libc++ has a debug mode that enables extra precondition checking. When Clang is built with libc++ in that special mode, a few of Clang's tests would fail with the libc++ assertion because Clang was not honoring the preconditions for std::stable_sort. However, Clang would not hit the precondition failure with any release mode STL, so the changes have no impact on users beyond ones in this very special circumstance.
