Some fixes for exponentiation which was recently introduced in #59894

  • Makes exponentiation right-associative. For example, a ** b ** c should be equivalent to a ** (b ** c), not (a ** b) ** c
  • Ensures that required parentheses are preserved in the compiled output. Parentheses are required when a unary operator is used in the base of the exponentiation, for example (-1) ** 3
