Hi,

To make sure our inlining of _Generic doesn't go crazy we added an in 
between declaration of the parameters used for _Generic selection. 
However, this will not work if the parameter being passed in is an array.
Since none of our intrinsics return pointers we do not need to use 
typeof here as we will never be able to nest intrinsics through this 
parameter. I also removed the unnecessary const pointers in mve_typeid.

Regression tested on arm-none-eabi.

Is this OK for trunk?
