Removed gratuitous cosmetic differences with the i386 version. This

Browse source 
mainly involves removing all __CC_SUPPORTS___INLINE__ ifdefs.  These
ifdefs are even less needed for amd64 than for i386, but the i386
atomic.h never had them.  The ifdefs here were just an optimization
of obsolescent compatibility cruft (__inline) for a null set of
compilers.  I think null sets of compilers should only be supported
in cases where this is more than an optimization, doesn't require
extensive ifdefs, and only involves not-so-obsolescent compatibility
cruft (plain inline here).
