<pre>Unfortunately, one of the tessellation stages (I forget which) still runs in
vec4 mode on Broadwell, and even if we supported scalar mode there are certain
cases where we need to use vec4 (Ken would know the details), so we have to
support fp64 on vec4 for Broadwell. There are some extra things that need to be
fixed about fp64 on vec4 mode, but I think that I've communicated most of them
in this bug.</pre>
