  Remove WANTflags

It meant to remove straitforward class upcast C to B (offset == 0), and
used where a compile-time boolean value required.

I couldn't think any problematic case that will be introduced by the constantly enabling the optimization.

  Make WANTvalue default

The difference 0 and WANTvalue was used in AndAndExp/OrOrExp to make error for the void expressions if value is required.

But today, the appearance of invalid void sub-expression is structly checked by Expresssion::rvalue() etc in each semantic() calls, so the check in optimize() is unnecessary.

Therefore, change the value of WANTvalue to 0 and make that the default behavior of optimize().
