[40/77] Use scalar_int_mode for extraction_insn fields
insv, extv and eztzv modify or read a field in a register or
memory. The field always has a scalar integer mode, while the
register or memory either has a scalar integer mode or BLKmode.
The mode of the bit position is also a scalar integer.
This patch uses the type system to make that explicit.
