[PATCH] 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:

2017-06-26 Walfred Tedeschi <walfred.tedeschi@intel.com>

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