Robert Findley fe725d9349 gopls/internal/regtest: simplify awaiting diagnostics from a change ... When awaiting diagnostics, we should almost always wrap expectations in a OnceMet(precondition, ...), so that tests do not hang indefinitely if the diagnostic pass completes and the expectations are still not met. Before this change, the user must be careful to pass in the correct precondition (or combination of preconditions), else they may be susceptible to races. This change adds an AllOf combinator, and uses it to define a new DoneDiagnosingChanges expectation that waits for all anticipated diagnostic passes to complete. This should fix the race in TestUnknownRevision. We should apply a similar transformation throughout the regression test suites. To make this easier, add a shorter AfterChange helper that implements the common pattern.
