SSE intrinsic may mulfunction using Clang 19 with -ffast-math (OR: Recommendation to add -fno-finite-math-only)

Steps to Reproduce
`{
static VectorRegister4Float v = MakeVectorRegisterFloat(4.0, -3.0, 2.0, -1.0f);
auto f = (VectorRegister4Float const& x) { return VectorAbs(x); };

static VectorRegister4Float a = f(v);
printf(“%f %f %f %f\n”, VectorGetComponent(a, 0), VectorGetComponent(a, 1), VectorGetComponent(a, 2), VectorGetComponent(a, 3));
}`When above code inserted into arbitrary runtime code, and is compiled using Clang 19 (regardless of platform) with FPSemanticsMode.Imprecise (hence with -ffast-math), the output is may NOT the correct absolute value.
