Install Windows crash dump handler before all else.
Apart from calling write_stderr() on failure, the handler depends on noPostgreSQL facilities. We have experienced crashes before reaching theformer call site. Given such an early crash, this change cannot hurtand may produce a helpful dump. Absent an early crash, this change hasno effect. Back-patch to 9.3 (all supported versions).Takayuki TsunakawaDiscussion:https://postgr.es/m/0A3221C70F24FB45833433255569204D1F80CD13@G01JPEXMBYT05
