Ian Romanick bac10ef4aa intel/fs: Add DP4A to get_lowered_simd_width
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.
