    intel/fs: Don't use automatic exec size inference · 1ca3a944

    The automatic exec size inference can accidentally mess things up if
    we're not careful.  For instance, if we have
    
    add(4)    g38.2<4>D    g38.1<8,2,4>D    g38.2<8,2,4>D
    
    then the destination register will end up having a width of 2 with a
    horizontal stride of 4 and a vertical stride of 8.  The EU emit code
    sees the width of 2 and decides that we really wanted an exec size of 2
    which doesn't do what we wanted.
