* findvar.c (read_var_value): Remove case for thread local storage
	variables.  It is now entirely handled by the dwarf2 location
	expression code.
	* printcmd.c (address_info): Ditto.
	* symtab.h (address_class): Remove LOC_THREAD_LOCAL_STATIC
	enumeration value.
	(struct symbol): Remove objfile field, which was used by
	LOC_THREAD_LOCAL_STATIC only.
	* dwarf2read.c (decode_locdesc): Remove is_thread_local variable.
	* dwarf2loc.h (struct dwarf2_loclist_baton): Add comment about
	usage of objfile pointer.
	* dwarf2loc.c (locexpr_describe_location): Add case to handle
	thread local variables.
	Add include of objfiles.h.
	* dwarf2expr.c (execute_stack_op): Add comments about thread local
