Tim Northover 14ff2df05c ARM: spot SBFX-compatbile code expressed with sign_extend_inreg ...

We were assuming all SBFX-like operations would have the shl/asr form, but
often when the field being extracted is an i8 or i16, we end up with a
SIGN_EXTEND_INREG acting on a shift instead. Simple enough to check for though.
