718c914e7b Fix evacuation of bytevectors with inline storage 
* libguile/bytevectors.c (make_bytevector): We were allocating these as
tagged pointerless, which means that the trace function wasn't being
called; whereas, it was necessary in the case of a relocation.  Instead,
allocate tagged if the collector supports object motion.

75f1f20031 Refactor relationship between gc_mutator_roots and threads 
* libguile/threads.c (guilify_self_1):
* libguile/whippet-embedder.h (gc_trace_mutator_pinned_roots): Make the
roots contain the thread.  This way sizeof(*thread) is the total
allocation size; if you pad the allocation with extra words, some of the
self-checks in nofl get borked.
