x86/asm: Annotate aliases
_key_expansion_128 is an alias to _key_expansion_256a, __memcpy to
memcpy, xen_syscall32_target to xen_sysenter_target, and so on. Annotate
them all using the new SYM_FUNC_START_ALIAS, SYM_FUNC_START_LOCAL_ALIAS,
and SYM_FUNC_END_ALIAS. This will make the tools generating the
debuginfo happy as it avoids nesting and double symbols.
