  Log Message:
  -----------
  [Clang] [Sema] Document invariant in Sema::AddOverloadCandidate (#135256)

Static analysis flagged 1 - ArgIdx in Sema::AddOverloadCandidate for its
potential to overflow.

Turns out this is intentional since when PO ==
OverloadCandidateParamOrder::Reversed Args.size() is always two, so this
will never overflow.

We document using an assert.
