f2ab172867 target/riscv: make ADD/SUB/OR/XOR/AND insn use arg lists 
manual decoding in gen_arith() is not necessary with decodetree. For now
the function is called trans_arith as the original gen_arith still
exists. The former will be renamed to gen_arith as soon as the old
gen_arith can be removed.

7a50d3e2ae target/riscv: Move gen_arith_imm() decoding into trans_* functions 
gen_arith_imm() does a lot of decoding manually, which was hard to read
in case of the shift instructions and is not necessary anymore with
decodetree.

b73a987b09 target/riscv: Convert RVXI arithmetic insns to decodetree 
we cannot remove the call to gen_arith() in decode_RV32_64G() since it
is used to translate multiply instructions.

for now only LUI & AUIPC are decoded and translated. If decodetree fails, we
fall back to the old decoder.
