riscv: zero registers when using register-wide operations
what was happening is that instructions like `lb` were only affecting the lower bytes of the register and leaving the top dirty. this would lead to situtations were `cmp_eq` for example was using `xor`, which was failing because of the left-over stuff in the top of the register.
with this commit, we now zero out or truncate depending on the context, to ensure instructions like xor will provide proper results.
