target-arm: Rename ARM_FEATURE_DIV to _THUMB_DIV
Rename the ARM_FEATURE_DIV feature bit to _THUMB_DIV, to
make room for a new feature switch enabling DIV in the ARM
encoding. (Cores may implement either (a) no divide insns
(b) divide insns in Thumb encodings only (c) divide insns
in both ARM and Thumb encodings.)
