[Patch]Option support to ARM MCU Cortex-M7 and related FPU

["Terry Guo" <terry dot guo at arm dot com>]

Hi there,

The attached patch implemented option support in Binutils to support new ARM
MCU announced at:
http://www.arm.com/about/newsroom/arm-supercharges-mcu-market-with-high-perf
ormance-cortex-m7-processor.php
http://www.arm.com/products/processors/cortex-m/cortex-m7-processor.php

Tested with Binutils regression test and no new regressions. Is it OK to
trunk?

BR,
Terry
