(HAVE___THREAD): Force it off for now---the per-thread cache uses

Browse source 
about 128KB of thread-local storage for each and every
	thread, even if a thread never ever needs to unwind its
	stack.  Seems a bit much.
(ALWAYS_INLINE): New macro which can be used to force inlining
	on compilers that support it.

(Logical change 1.132)
