Keith Randall 10d3b13551 cmd/compile: ensure stenciled function bodies are nonempty
Our compiler gets confused between functions that were declared
with no body, and those which have a body but it is empty.

Ensure that when stenciling, we generate a nonempty body.

The particular test that causes this problem is in
cmd/compile/internal/gc/main.go:enqueueFunc. It thinks that if
a function has no body, then we need to generate ABI wrappers for
it, but not compile it.

Fixes #49524
