2019-03-13target/riscv: Remove manual decoding from gen_load()Bastian Koppelmann
With decodetree we don't need to convert RISC-V opcodes into to MemOps as the old gen_load() did. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Bastian Koppelmann <kbastian@mail.uni-paderborn.de> Signed-off-by: Peer Adelt <peer.adelt@hni.uni-paderborn.de>

We now utilizes argument-sets of decodetree such that no manual decoding is necessary. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Bastian Koppelmann <kbastian@mail.uni-paderborn.de> Signed-off-by: Peer Adelt <peer.adelt@hni.uni-paderborn.de>

trans_jalr() is the only caller, so move the code into trans_jalr().
