OK.  Here's a patch that combines your casts for 64-bit builds with a simple 
solution to the pointers-stored-as-ints problem.  I would really love to replace 
all the code involved in the latter problem, but it will be a while before I can 
get to it, and I didn't want to leave the 64-bit builds broken in the meantime. 
  I just changed the code to use pointer fields in the Xtensa-specific 
tc_frag_data structure.

I tested this with --enable-64-bit-bfd builds on both x86_64-unknown-linux-gnu 
and i686-pc-linux-gnu hosts.  Committed on the mainline and 2.16 branch.

	* config/tc-xtensa.h (struct xtensa_frag_type): Add lit_frchain field.
	* config/tc-xtensa.c (xg_translate_sysreg_op,
	xtensa_translate_old_userregs_ops,
	xtensa_find_unaligned_branch_targets,
	xtensa_find_unaligned_loops, xtensa_fix_close_loop_end_frags,
	relax_frag_add_nop): Support 64-bit host.
	(xtensa_mark_literal_pool_location, xtensa_move_literals): Use
	tc_frag_data lit_frchain and lit_seg fields instead of fr_var.
