Benjamin Maxwell c3260c65e8 [IR] Add llvm.sincos intrinsic (#109825) ...

This adds the `llvm.sincos` intrinsic, legalization, and lowering.

The `llvm.sincos` intrinsic takes a floating-point value and returns
both the sine and cosine (as a struct).

```
declare { float, float }          @llvm.sincos.f32(float  %Val)
declare { double, double }        @llvm.sincos.f64(double %Val)
declare { x86_fp80, x86_fp80 }    @llvm.sincos.f80(x86_fp80  %Val)
declare { fp128, fp128 }          @llvm.sincos.f128(fp128 %Val)
declare { ppc_fp128, ppc_fp128 }  @llvm.sincos.ppcf128(ppc_fp128  %Val)
declare { <4 x float>, <4 x float> } @llvm.sincos.v4f32(<4 x float>  %Val)
```

The lowering is built on top of the existing FSINCOS ISD node, with
additional type legalization to allow for f16, f128, and vector values.
