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.

bce8a342a1 target/riscv: Remove manual decoding from gen_store() 
With decodetree we don't need to convert RISC-V opcodes into to MemOps
as the old gen_store() did.
