[Bug c++/41959] New: Vector type name mangling is size ambiguous

[rth at gcc dot gnu dot org]

---
#include <x86intrin.h>
void f(__m128) { }
void f(__m256) { }
---
Build with the -mavx flag to enable 32-byte vectors.

z.s: Assembler messages:
z.s:22: Error: symbol `_Z1fU8__vectorf' is already defined

This because the vector mangling does not include the size of the vector,
and thus __m128 and __m256 mangle to the same thing.
