Policy class for configuring gmx::Allocator, to manage allocations of aligned memory for SIMD code.
|Return the alignment size.|

Allocate memory aligned to alignment() bytes.
bytes Amount of memory (bytes) to allocate. It is valid to ask for 0 bytes, which will return a non-null pointer that is properly aligned and padded (but that you should not use).
- Valid pointer if the allocation worked, otherwise nullptr.
The memory will always be aligned to 128 bytes, which is our estimate of the longest cache lines on architectures currently in use. It will also be padded by the same amount at the end of the area, to help avoid false cache sharing.
