[PATCH] D44175: Add std:: to begin and end in drop_begin

[Krzysztof Parzyszek via Phabricator via llvm-commits]

Compiling this code gives me "undeclared symbol" errors for `begin` and `end` in `drop_begin`:

  if (const auto *A = dyn_cast<SCEVAddExpr>(R->getStart())) {
    if (const auto *C = dyn_cast<SCEVConstant>(A->getOperand(0))) {
      SmallVector<const SCEV*,2> Ops1(drop_begin(A->operands(), 1));
      const SCEV *NA = SE->getAddExpr(Ops1, A->getNoWrapFlags());
    }
  }

This change is intended to fix that.
