Some instructions contain fields that are either an address or a value
of some type based on the content of other fields, such as clear color
values vs address. That works fine if these fields are in the less
significant dword, the lower 32 bits of the address, because they get
OR'ed with the address. But if they are in the higher 32 bits, they get
discarded.
On Gen10 we have fields that share space with the higher 16 bits of the
address too. This commit makes sure those fields don't get discarded.
