Matthew Malcomson 4934a27c8c [binutils][arm] arm support for ARMv8.m Custom Datapath Extension 
This patch is part of a series that adds support for the Armv8.m
ARMv8.m Custom Datapath Extension to binutils.

This patch introduces the Custom Instructions Class 1/2/3 (Single/
Dual, Accumulator/Non-accumulator varianats) to the arm backend.

The following Custom Instructions are added: cx1, cx1a,
cx1d, cx1da, cx2, cx2a, cx2d, cx2da, cx3, cx3a, cx3d, cx3da.

Specification can be found at
https://developer.arm.com/docs/ddi0607/latest

This patch distinguishes between enabling CDE for different coprocessor
numbers by defining multiple architecture flags.  This means that the
parsing of the architecture extension flags is kept entirely in the
existing code path.

We introduce a new IT block state to indicate the behaviour of these
instructions.  This new state allows being used in an IT block or
outside an IT block, but does not allow the instruction to be used
inside a VPT block.
We need this since the CX*A instruction versions can be used in IT
blocks, but they aren't to have the conditional suffixes on them.  Hence
we need to mark an instruction as allowed in either position.

We also need a new flag to objdump, in order to determine whether to
disassemble an instruction as CDE related or not.

Successfully regression tested on arm-none-eabi, and arm-wince-pe.
