[PATCH 1/2][AArch64] Add missing support for poly64x1_t

[Tamar Christina]

Hi all,

This fixes a bug in the name mangling which prevented mangling
of functions with return type void and arguments that require
any qualifiers.  e.g. void(unsigned int, unsigned int).  

Ran regression tests on aarch64-none-linux-gnu.

Ok for trunk?

Thanks,
Tamar
