Add ARM32 support on the translator (#561)
* Remove ARM32 interpreter and add ARM32 support on the translator * Nits. * Rename Cond -> Condition * Align code again * Rename Data to Alu * Enable ARM32 support and handle undefined instructions * Use the IsThumb method to check if its a thumb opcode * Remove another 32-bits check
