This class used to be required if you wanted an object to be allocated with a specific

alignment. ALIGN16 and ALIGN16_POST are not actually sufficient for this because they
|
|
guarantee that the globals, statics, locals, and function parameters are appropriately
|
|
aligned they do not affect memory allocation alignment.
|
|
However this class is usually not needed because as of 2012 our policy is that our
|
|
allocator should take care of this automatically. Any object whose size is a multiple
|
|
of 16 will be 16-byte aligned. Existing uses of this class were not changed because
|

the cost/benefit did not justify it.
