About compiler changes:

I think you can add a new common ideal node super class (CountBits ?)
since all new ideal nodes and PopCount have the same bottom_type and ideal_req
instead of repeating the same declarations.

Also why you keep default 'false' values for Count flags?

I will look on assembler next.
