Subject: MIPS: Actually decode JALX in `__compute_return_epc_for_insn'

From: Maciej W. Rozycki <[email protected]>

commit a9db101b735a9d49295326ae41f610f6da62b08c upstream.

Complement commit fb6883e5809c ("MIPS: microMIPS: Support handling of delay slots.") and actually decode the regular MIPS JALX major instruction opcode, the handling of which has been added with the said commit for EPC calculation in `__compute_return_epc_for_insn'.
