odin: Implement multipliers where one of the operands has a size of 1
using hard multipliers.
For multipliers where one of the operands has a size of 1. The output
size is equal to the larger operand size and not the sum of the operand
sizes as usual. This special case causes a segmentation fault. A temporary
fix is implementing those multipliers using hard multipliers.
