MIPS/gas: Reject $0 as source register for DAUI instruction
The MIPS64R6 TRM requires that the source register for DAUI
not be r0.

"Alphabetical List of Instructions", pp. 67-68.
gas/
* testsuite/gas/mips/r6-branch-constraints.s: Rename to ...
* testsuite/gas/mips/r6-reg-constraints.s: this and add test
case for DAUI.
