gollvm: tree integrity checking enhancements

Integrity checker now has an explicit "batch" and "incremental"
mode. Batch mode processes an entire subtree, whereas incremental mode
looks only at a node's immediate children. Bridge uses batch mode at
statement creation time, incremental mode at expression creation time
(performing the check here identifies problems earlier on, making for
easier debugging). For incremental mode, rework things to avoid "false
positives" (reporting tree sharing that in fact be will be repaired
later on). Also, disable checking during tree repair/cloning
operations, since things can be in an inconsistent state at that
point.
