Add simulation of MUL and NEG instructions to AArch64 simulator.

	* cpustate.c: Remove spurious spaces from TRACE strings.
	Print hex equivalents of floats and doubles.
	Check element number against array size when accessing vector
	registers.
	* memory.c: Trace memory reads when --trace-memory is enabled.
	Remove float and double load and store functions.
	* memory.h (aarch64_get_mem_float): Delete prototype.
	(aarch64_get_mem_double): Likewise.
	(aarch64_set_mem_float): Likewise.
	(aarch64_set_mem_double): Likewise.
	* simulator (IS_SET): Always return either 0 or 1.
	(IS_CLEAR): Likewise.
	(fldrs_pcrel): Load and store floats using 32-bit memory accesses
	and doubles using 64-bit memory accesses.
	(fldrd_pcrel, fldrs_wb, fldrs_abs, fldrs_scale_ext): Likewise.
	(fldrd_wb, fldrd_abs, fsturs, fsturd, fldurs, fldurd): Likewise.
	(fstrs_abs, fstrs_wb, fstrs_scale_ext, fstrd_abs): Likewise.
	(fstrd_wb, fstrd_scale_ext, store_pair_float): Likewise.
	(store_pair_double, load_pair_float, load_pair_double): Likewise.
	(do_vec_MUL_by_element): New function.
	(do_vec_op2): Call do_vec_MUL_by_element.
	(do_scalar_NEG): New function.
	(do_double_add): Call do_scalar_NEG.
