core: fix TODOs related to TLB maintenance in the pager
Invalidate TLBs for target references instead of invalidating the
whole tables.
Some changes affect places where several references are modified and
must be invalidated in the TLBs. This change aims at lowering the
synchronization barrier required before/after the TLB maintenance
operations.
