/*
These will need a complete rewrite for armeabi:
* ADDS is not supported in Thumb16 mode
* Thumb does not support conditional execution (MOVCS/MOVCC)
* armv5te+xscale does not support UMLAL
ADDS - add and set condition flags (bottom of page 16, arm_inst.pdf)
MOVCS / MOVCC - move if carry bit is set / clear
UMLAL RdLo, RdHi, Rn, Rm - unsigned multiply Rn and Rm, then
add resulting 64-bit value to (RdHi,RdLo)
