While working on cooperative matrix support, I noticed some invalid
DP4A instructions being generated.
dp4a(32) g33<1>UD g21<8,8,1>UD g1.0<0,1,0>UD g9<1,1,1>UD
This violates the constraint that the destination or a source can only
access two consecutive GRFs.
I'm a little surprised that validation didn't catch this. Perhaps
because it's a 3 source instruction? Either way, it seems like a bigger
project to fix that.
