vm: int-int fast paths for OpDiv, OpMod, OpBitAnd/Or/Xor, OpShl, OpShr

Same pattern as OpAdd/OpSub/OpMul: when both operands are ZtInt,
compute inline and skip the generic OperatorMath / OperatorMathLogic
dispatch (which constructs a phpv.Val interface, GMP-overload
checks, etc.). Mixed types still go through the generic path.

Each fast path includes the corresponding guard:
* OpDiv: bi != 0; if ai/bi has a remainder or hits the
  math.MinInt64/-1 overflow, fall through to opDiv (produces float).
* OpMod: bi != 0; MinInt64 % -1 falls through (operatorMathLogic
  returns ZInt(0) for that case but goes via the generic path).
* OpShl/OpShr: bi >= 0; bi >= 64 produces 0 / sign-extension as
  per PHP semantics.
