Thumb2 load/store fixups don't set the thumb bit.
Thumb2 load/store fixups don't set the thumb bit.

Load/store instructions w/ a fixup to be relative a function marked as thumb
don't use the low bit to specify thumb vs. non-thumb like interworking
branches do, so don't set it when dealing with those fixups.
