reinterpret_cast error

I get compiler errors from the reinterpret_casts in common.h. I've tried GCC-{8,910,}. clang-{9,11}, and visual studio. What compiler is supported?

```
C:\Users\snaph\Downloads\libmoonage-master\common.h:18:100: warning: ignoring attributes applied to dependent type 'T' without an associated declaration [-Wattributes]
template using Vector128 = T __attribute__((ext_vector_type(16 / sizeof(T)), unaligned));
