[PATCH v2 09/11] RISC-V: Add disassembler tests for Zdinx regs

[Tsukasa OI]

This commid adds disassembler tests for invalid Zdinx register numbers
(make sure that we don't disassemble invalid encodings).

gas/ChangeLog:

	* testsuite/gas/riscv/zdinx-32-regpair-dis.s: New test to make
	sure that invalid encoding is not disassembled.
	* testsuite/gas/riscv/zdinx-32-regpair-dis.d: Likewise.
