[PATCH][GCC][Arm]: MVE: Add C++ polymorphism and fix some more issues

Hi,

This patch adds C++ polymorphism for the MVE intrinsics, by using the 
native C++ polymorphic functions when C++ is used.

It also moves the PRESERVE name macro definitions to the right place so 
that the variants without the '__arm_' prefix are not available if we 
define the PRESERVE NAMESPACE macro.

This patch further fixes two testisms that were brought to light by C++ 
testing added in this patch.

Regression tested on arm-none-eabi.

Is this OK for trunk?
