MIPS16/opcodes: Correct I64/SDRASP opcode's ISA membership
Limit the `SD ra, offset(sp)' instruction (I64/SDRASP major/minor
opcode) to the MIPS III rather than MIPS I ISA. This is a 64-bit
instruction requiring a 64-bit ISA. This bug has been there since
forever.
opcodes/
* mips16-opc.c (mips16_opcodes): Set membership to I3 rather
than I1 for the SP-relative "sd"/$ra entry (SDRASP minor
opcode).
gas/
* testsuite/gas/mips/mips16-sdrasp.d: New test.
* testsuite/gas/mips/mips16-sdrasp.l: New stderr output.
* testsuite/gas/mips/mips16-sdrasp.s: New test source.
* testsuite/gas/mips/mips.exp: Run the new test.
