Summary0015585: Add support for the if / else construct to generator expressions
DescriptionIt's often desirable to provide content for both branches, e.g.:

    $<CONFIG:Debug:-O0?-O2>

Right now code should like this:

        $<CONFIG:Debug:-O0>$<$<NOT:$<CONFIG:Debug>>:-O2>

Which is beyond being readable.

 +1. It is my experience that if the test expression is false, I rarely want the result to be an empty string; usually, I have a second value I want to use in this case.

Before this ticket was pointed out to me, I had already created a question on Stack Overflow: http://stackoverflow.com/q/34393562/52041 [^] . Interestingly, I used almost the identical example there.
