ARM: Use r4 for stack overflow check to reduce code size. The code savings are 2 bytes per stack overflow check but this can be rounded up or down to the kArmAlignment (8). Current testing shows the boot image size difference for aosp_taimen-userdebug arm boot*.oat as - before: 17939352 - after: 17881764 (-56KiB, -0.3%) Test: Pixel 2 XL boots. Test: testrunner.py --target -t 018-stack-overflow Bug: 71627785 Change-Id: Icb732b59e9e681b29790e7e07de2710da33245b1
