Fix unaligned allocation memory for 64-bit platforms

[GermanAizek]

More info about "Fix unaligned allocation" with my benchmarks in dav1d AV1 decoder:

A similar principle can be applied to optimize memory allocation and deallocation by aligned blocks.

Hello @GermanAizek,

thank you for reporting the issue. Could you please update the description using the template given in #131 ?

Please add your content in the template fields enclosed with {{ and }} and remove the curly braces.

Could you please mark the checkboxes in the Extra fields section too by replacing the space with an x?

Thanks for your help.

I'm moving this to X11Libre Ideas · Discussions · GitHub since there are still some open questions. Also the real value should be shown by numbers and outweight the risk of breaking things significantly.
