[OpenJDK 2D-Dev] RFC: 7019861 + workaround + minor optimization

[Jim Graham]

Hi Denis,

Yes, that was the point of my original question.  I was asking how you 
felt about the dead code, apologies that it took so long to get on the 
same page.  I don't have a strong opinion there, I was just making you 
aware that there was more dead code.  Another option would be to move 
just the switch statement into a secondary shared function which might 
be small enough not to trigger that compiler bug.

But, I'll leave those decisions up to you.  I was just pointing out that 
you missed some potentially dead code...
