ARM: 6286/1: fix Thumb-2 decompressor broken by "Auto calculate ZRELADDR"
"ARM: Auto calculate ZRELADDR and provide option for exceptions" broke the Thumb-2 decompressor because it removed an entry in the LC0 table but didn't adjust the offset the Thumb-2 code uses to load the SP from that table. Fix it, and also change the ARM code to use the separate SP-load since ARM instructions that include the SP in the LDM register list are deprecated.
