Add UBSAN build option and fix undefined behaviour errors.

1. The assembler tried to write to unaligned addresses but memcpy fixes this.
2. The InstKind and OperandKind enums allowed target specific kinds that did not
   fall in the defined range. Defining the maximum target kind in the enum sorts
   this problem.
