…fter optimization. wip: make vsetvl* write to CSR regs and vector instructions read from it to prevent wrong scheduling
Previously, we had to set lmul manually for each optimization region. SLOTHY was already able to set LMUL when it parsed a vsetvl* instruction. However, there were no constraints that connected vector incstructions to their corresponding vsetvl* instruction. This has been modeled now, as vsetvl* now has a CSR reg as output and all vector instructions inherntly read from that CSR reg. Moreover, all vector instructions store the lmul value they are constrained to as well.
…tions are being used
…tore sew similarly to lmul per instruction so it survives parsing
