core: added selval(evalexpr, valexp1, valexpr2)

- this is a core statement that return the 2nd parameter if the 1st
parameter is evaluated to true, or 3rd parameter if the 1st parameter is
evaluated to false
- it can be considered a core function that is equivalent of ternary
condition/operator
- example:
  $var(x) = selval($Ts mod 2, "true/" + $ru, "false/" + $rd);
- the first parameter is a conditional expression, like those used for
IF, the 2nd and 3rd parameters can be expressions like those used in the
right side of assignments
