These special cases were introduced in Go 1.10. For auto-updating code
from Go 1.9 and earlier, use the cftype or jni rewrites in the Go fix tool:

	go tool fix -r cftype <pkg>
	go tool fix -r jni <pkg>

It will replace nil with 0 in the appropriate places.

The EGLDisplay case was introduced in Go 1.12. Use the egl rewrite
to auto-update code from Go 1.11 and earlier:

	go tool fix -r egl <pkg>

	// stubs and reserve a PLT slot.

	// 1) The call site is a "bl x" where genpltstub rewrites it to
	//    "bl x_stub". Depending on the properties of the caller
	//    (see ELFv2 1.5 4.2.5.3), a nop may be expected immediately
	//    after the bl. This nop is rewritten to ld r2,24(r1) to
	//    restore the toc pointer saved by x_stub.
