RISC-V allows unaligned memory reads

li x1, 0x11223344
li x2, 0x55667788
sw x1, 0(zero)
sw x2, 4(zero)
lw x3, 2(zero)

should have the value of x3 be 0x77881122

This is not necessary for the exercises, but in order to be spec compliant the byte aligned memory branch may be utilized where this feature has been implemented. This will not be merged until the semester is over at I don't like testing in production.

I am experiencing the issue described here: chipsalliance/chisel#606.

btw I am defining io's like:
val io = IO(new Bundle { ... })

The proposed fix for it is already part of build.sbt (adding -Xsource:2.11 to the scalacOptions. Any ideas? I am using Ubuntu 18.04
