Only evaluate stms once in the repl

Steps to reproduce:

{ printi(120); printc('\n'); }

1 + 1

---

Expected result:

The number 120 (followed by a LF) should be printed in the repl after step 1. After step 2 the evaluated expression should be displayed (in this case 2).

---

Actual result:

> { printi(120); printc('\n'); }
120
> 1 + 1
120
int res0 = 2;
> 

The 120 is printed after step 2.

Description:

Statements (with a few exceptions: new and del) are evaluated each time a statement or an expression is evaluated in the repl.
