Fix for aarch64 sim sxtl/uxtl insns, plus another fix for addv.

	sim/aarch64/
	* simulator.c (do_vec_ADDV): Mov val declaration inside each case,
	with type set to input type size.
	(do_vec_xtl): Change bias from 3 to 4 for byte case.

	sim/testsuite/sim/aarch64/
	* bit.s: Change cmp immediates to account for addv bug fix.
	* cmtst.s, ldn_single.s, stn_single.s: Likewise.
	* xtl.s: New.
