Add command-line option for SSBS
[AArch64] Add command-line option for SSBS

Summary:
SSBS (Speculative Store Bypass Safe) is only mandatory from 8.5
onwards but is optional from Armv8.0-A. This patch adds testing for
the ssbs command line option, added to allow enabling the feature
in previous Armv8-A architectures to 8.5.
