[Patch ARM Refactor Builtins 6/8] Add some tests for "poly" mangling

[James Greenhalgh]

Hi,

The poly types end up going through the default mangler, but only
sometimes.

We don't want to change the mangling for poly types with the next patch in
this series, so add a test which should pass before and after.

I've checked that the new tests pass at this stage of the patch series,
and bootstrapped on arm-none-linux-gnueabihf for good luck.

OK?

Thanks,
James
