[X86][SSE] Improve recognition of i64 sitofp conversions that can be performed as i32 (PR29078)
Until AVX512DQ we only support i64/vXi64 sitofp conversion as scalars.
This patch sees if the sign bit extends far enough that we can truncate to a i32 type and then perform sitofp without loss of precision.
