This is used from the assembly implementation of the thread dispatch epilogue variant to copy the exception frame on to the thread stack. I suppose it could be done with memcpy instead since that is what the AArch64 implementation compiles down to.

If it is not used in architecture-independent code, then there should be no _CPU_* interface. The _CPU_* stuff is for architecture-independent code which needs to use an architecture-dependent implementation.
