i965/disasm: Properly disassemble jump targets on Gen4-5.

Previously, our dissasembly for flow control instructions looked like:

0x00000040: else(8)         ip          65540D     { align16 switch };

It didn't print InstCount properly for ELSE/ENDIF, and didn't even
attempt to disassemble PopCount.

Now it looks like:

0x00000040: else(8)         Jump: 4     Pop: 1     { align16 switch };

which is much more readable.
