Allow empty FOR statements

[GoogleCodeExporter]

Example:

  for(;;)
  {
      break;
  }

Or 

  for(;i < 2;)
  {
      i = 5;
  }

This can be easily done in function ParseFor by looking ahead in the parse tree.

Example just for first statement in FOR:

Change this:

    if (ParseStatement(Parser, TRUE) != ParseResultOk)
        ProgramFail(Parser, "statement expected");

To:

    if (LexGetToken(Parser, NULL, FALSE) == TokenSemicolon)
    {
        LexGetToken(Parser, NULL, TRUE);
    }
    else if (ParseStatement(Parser, TRUE) != ParseResultOk)
    {
        ProgramFail(Parser, "statement expected");
    }

Similar concept can be applied to all FOR statements.
