Cleanup ALIGNED_POINTER:
o add to platforms where it was missing (arm, i386, powerpc, sparc64, sun4v) o define as "1" on amd64 and i386 where there is no restriction o make the type returned consistent with ALIGN o remove _ALIGNED_POINTER o make associated comments consistent Reviewed by: bde, imp, marcel Approved by: re (kensmith)
