runtime: setg after sigFetchG In the normal case, sigFetchG just returns the G register. But in the case that sigFetchG fetches the G from somewhere else, the G register still holding an invalid value. Setg here to make sure they match. This is particularly useful because setGsignalStack, called by adjustSignalStack from sigtrampgo before setg to gsignal, accesses the G register. Should fix #35249.
