gdb - avx512: tests were failing due to missing memory aligment.

Test was running on a fault during code execution.  Analysis have shown
that the wrong instruction had been used.  An instruction that takes
not alligned memory is more appropriated for the task.

ChangeLog:

2017-09-20  Walfred Tedeschi  <walfred.tedeschi@intel.com>

gdb/testesuite/ChangeLog:
	* gdb.arch/i386-avx512.c (move_zmm_data_to_reg): Use
	vmovups instead vmovaps.
	(move_zmm_data_to_memory): Use vmovups instead vmovaps.
