Allow specifying an allocation alignment to Allocate() that works
similarly to the alignment parameter to aligned_alloc(), e.g. the
alignment parameter must be a power-of-two smaller than size. Unlike
aligned_alloc it doesn't verify that the size is a multiple of alignment
since that's not enforced by some functions like posix_memalign.

Default alignment behavior stays the same if no alignment is specified.
