* entc/gen/template/dialect/sql: cleaning up isSQLConstraintError in generated ent.go to use new sqlgraph IsConstraintError checks. Adding IsFK and IsUniqueness methods to the generated ent.ConstraintError (on SQL dialects) struct to allow users to glean more information about the specific constraint violation. Fixes #1310 * fix indentation in tmpl file regen files rm new methods from generated code * regen
