florian 83fb4c289d * patch by Nico Erfurth: Implement FoldShiftProcess Peephole optimizer for ARM
This optimizer folds shift/roll operations into following data
instructions.

It will change code like:

mov r0, r0, lsl #16
add r1, r0, r1

into

add r1, r1, r0, lsl #16

Source registers will be reordered when necessary, also SUB/SBC will be
replaced with RSB/RSC and vice versa when reordering is required.

It could be expanded to support more operations like LDR/STR.
