The amdgpu target uses vector types in various places. The vector types
can be used on all architectures, there is no associated target feature
that needs to be enabled.
The largest vector type found in LLVM intrinsics is `v32i32`
(`[32 x i32]`) for mfma intrinsics. Note that while this intrinsic is
only supported on some architectures, the vector type itself is
supported on all architectures.
