i965: Don't print source registers for Broadwell flow control.
The bits which normally contain the source register descriptions
actually contain the JIP/UIP jump targets, which we already printed.
Interpreting JIP/UIP as source registers results in some really creepy
looking output, like IF statements with acc14.4<0,1,0>UD sources.
