Log Message:
0.8.3.11
	 Inline allocation for GENCGC ...

	 ... add allocation-inline, which does direct access to 
	 allocation region fields based on %fs (for threads)
	 or &boxed_region (unithread), falling through to 
	 assembler routines and eventual call to alloc() 
	 if we've run out of space in the region

	 ... relevant assembler glue, partly borrowed from CMUCL 
	 but with changes to do thread-local access when appropriate

	 ... patch alloc() to use boxed_region instead of
	 all_threads->region on unithread builds

	 ... clean up cut/pasted code in allocation-notinline
