AsmPrinter: Take range in DwarfExpression::AddExpression(), NFC

Previously `DwarfExpression::AddExpression()` relied on
default-constructing the end iterators for `DIExpression` -- once the
operands are represented explicitly via `MDExpression` (instead of via
the strange `StringRef` navigator in `DIHeaderIterator`) this won't
work.  Explicitly take an iterator for the end of the range.
