This patch defines the representation that will be used for the SVE register state in the signal frame, and implements support for saving and restoring the SVE registers around signals. The same layout will also be used for the in-kernel task state. Due to the variability of the SVE vector length, it is not possible to define a fixed C struct to describe all the registers. Instead, Macros are defined in sigcontext.h to facilitate access to the parts of the structure.
