merge revision(s) 51410: [Backport #11396]

	* symbol.h (struct RSymbol): add hashval field

	* symbol.c (dsymbol_alloc): setup hashval field once

	* hash.c (rb_any_hash): return RSymbol->hashval directly

	* common.mk: hash.o depends on symbol.h
	  Thanks to Bruno Escherl <bruno@escherl.net> for the bug report
