faada5f110 Mask off LSBs of sepc/mepc/stvec
Therefore, they cannot generate misaligned instruction exceptions.
When a misaligned instruction exception does occur, mbadaddr
retains the misaligned PC bits, so no information is actually lost.

543ac91cf2 Misaligned fetches can't happen at the I$ anymore
They are caught before the I$ ever sees them, so leverage that fact.
