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

Instruction Set Manual", Imagination Technologies Ltd., Document
Number: MD00087, Revision 6.06, December 15, 2016, Section 3.2
"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.
* testsuite/gas/mips/r6-branch-constraints.l: Rename to ...
* testsuite/gas/mips/r6-reg-constraints.l: this and add test
for DAUI.
* testsuite/gas/mips/mips.exp: Rename test from
r6-branch-constraints to r6-reg-constraints.
opcodes/
* mips-opc.c (mips_builtin_opcodes): Change source register
constraint for DAUI.
