BE targets therefore use ST1D instead of the normal STR for those registers (but not for others). That difference is already tested elsewhere and isn't important for the SME tests. This patch therefore restricts the affected tests to LE. Tested on aarch64-linux-gnu and aarch64_be-elf, pushed to trunk.
