target/microblaze: Convert dec_add to decodetree

Adds infrastrucure for translation of instructions, which could
not be added before their first use.  Cache a temporary which
represents r0 as the immediate 0 value, or a sink.

Move the special case of opcode_0_illegal from old_decode()
into decodetree as well, lest this get interpreted as add.
