vm: int-int fast paths for arithmetic and comparison ops

OpAdd, OpSub, OpMul, OpCmpEq/Ne/Id/Nid/Lt/Le/Gt/Ge inline the int-int
case directly in the dispatch loop. Mixed-type operands still go
through the generic OperatorMath / OperatorCompare path.

Adds a small intIntFast / pushBoolReplace2 helper pair so each op
case stays readable.

Benchmarks (single-machine; same hardware; 1s benchtime):

  Arithmetic   55.8 ms (AST)  ->  19.8 ms (VM)   2.82x
  FunctionCalls 22.0 ms       ->  15.7 ms        1.40x
  Fibonacci    34.5 ms        ->  21.7 ms        1.59x
  ArrayOps     14.7 ms        ->   9.4 ms        1.57x
  StringConcat 21.6 ms        ->  17.3 ms        1.25x

The largest jump is on integer-heavy loops; Fibonacci improved from
1.32x to 1.59x because every recursive base-case branch is now an
inline ai <= 1 compare.
