Please review 7178670: runtime/7158800/BadUtf8.java fails in SymbolTable::rehash_table

[Coleen Phillimore]

After some discussions about the preserving shared state in move_to, it 
occurred to me that after rehashing, the shared entries were no longer 
last in the buckets.   The walking in StringTable and SymbolTable 
assumed this.    I also added more of a comment about preserving the 
state.  It could be nicer code and safer but it would also introduce 
some risk or possible performance impact.    These are the latest 
webrevs which I've tested with rehash_count=2 and rehash_multipier=1 to 
make it rehash a lot.
