Commit e677724 (arm: Fix setjmp) added code to fix compilation of the setjmp code path with thumv1. Unfortunately it missed a constraint that the adr instruction can only refer to 4 byte aligned offsets.
So this patch adds the required alignment hooks to make compilation work again even when setjmp doesn't happen to be 4 byte aligned.
