Hi,  
It seems the sort function allocates twice more memory in master vs 1.8.3:

```julia
using BenchmarkTools
x = rand(10^8);
@btime sort($x);

```

In 1.8.3 I get 2 allocations 762 MiB vs 6 allocations 1.49GiB in master.  
Is that considered a regression and will be addressed?  
I see that the time spent is improving from 10.2s to 6.2s.  
Thank you

Should I maybe open an issue on github?
