gollvm: introduce nil check size threshold

Support for configuring size threshold for nil checks introduced
by the front end (requires corresponding gofrontend change
https://go-review.googlesource.com/c/gofrontend/+/80996).
Also in this patch is a small set of tweaks to the tree integrity
checker (better unit tests, support for unsharing conditional exprs).
