Mike Pall 046129dbdd Fix rechaining of pseudo-resurrected string keys. 
This is a serious bug. But extremely hard to reproduce, so it went
undetected for 8 years. One needs two resurrections with different
main nodes, which are both in a hash chain which gets relinked on
key insertion where the colliding node is in a non-main position. Phew.

Thanks to lbeiming.

Mike Pall ab45481199 No longer let the GC replace dead keys with the LJ_TDEADKEY tag. 
Important: this changes the semantics of the write barrier!
Carefully read the big comment block in lj_obj.h
This helps HREFK key slot specialization and allows safely hoisting
HREF/HREFK across GC steps, too (fix for a barely reproducible bug).
Dead keys are only removed during a table resize (as before).
