Splittable functions ensure there's some amount of space on the stack
for nosplit functions to run in and the linker checks that any static
chain of nosplit function calls cannot exceed this bound.

Any function with a `//go:nosplit` annotation should explain why it is
nosplit in its documentation comment.
