Chris Kay 4e04478aac arch: Enable `FEAT_SB` for supported non-Armv8.5-A platforms ... The speculation barrier feature (`FEAT_SB`) was introduced with and made mandatory in the Armv8.5-A extension. It was retroactively made optional in prior extensions, but the checks in our code-base do not reflect that, assuming that it is only available in Armv8.5-A or later. This change introduces the `ENABLE_FEAT_SB` definition, which derives support for the `sb` instruction in the assembler from the feature flags passed to it. Note that we assume that if this feature is enabled then all the cores in the system support it - enabling speculation barriers for only a subset of the cores is unsupported.
