Rollup merge of #131551 - taiki-e:ppc-asm-vreg-inout, r=Amanieu
Support input/output in vector registers of PowerPC inline assembly

This extends currently clobber-only vector registers (`vreg`) support to allow passing `#[repr(simd)]` types as input/output.

| Architecture | Register class | Target feature | Allowed types |
| ------------ | -------------- | -------------- | -------------- |
| PowerPC      | `vreg` | `altivec` | `i8x16`, `i16x8`, `i32x4`, `f32x4` |
| PowerPC      | `vreg` | `vsx` | `f32`, `f64`, `i64x2`, `f64x2` |

In addition to floats and `core::simd` types listed above, `core::arch` types and custom `#[repr(simd)]` types of the same size and type are also allowed. All allowed types and relevant target features are currently unstable.
