CPU optimization gets its own files in which to fill-in optimizable routines. Some pointless #if 0's for profiling need removal. Those macros are empty if not profiling. Force some functions that are undesirable to be force-inlined by the compiler to be not inlined. Change-Id: Ia7b7e45380d7efb20c9b1a4d52e05db3ef6bbaab
