          Issue ID: 22056
           Summary: [Reg 2.074] std.traits.isFloatingPoint, isNumeric,
                    isUnsigned, & isSigned should never be true for SIMD
                    vectors

Below code fails from 2.074 onward:

---
import core.simd : int4, uint4, float4;
import std.traits;

static assert(!isFloatingPoint!float4);
static assert(!isNumeric!float4);
static assert(!isSigned!float4);
static assert(!isNumeric!int4);
static assert(!isSigned!int4);
static assert(!isNumeric!uint4);
static assert(!isUnsigned!uint4);
---

Note that in 2.074 isIntegral remained false for uint4 and int4, creating an
inconsistency.
