[PATCHv2] fix Thumb-2 decompressor broken by "Auto calculate ZRELADDR"

[Rabin Vincent]

"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.

v2: don't need separate code for ARM and THUMB since they're now
    the same.
