bug

• [bug] [autogenerate] [regression] Fixed regression caused by #879 released in 1.7.0 where the
  ".info" dictionary of Table would not render in autogenerate create
  table statements. This can be useful for custom create table DDL rendering
  schemes so it is restored.

  References: #1329

• [bug] [typing] Improved typing in the
  EnvironmentContext.configure.process_revision_directives
  callable to better indicate that the passed-in type is
  MigrationScript, not the MigrationOperation base class,
  and added typing to the example at cookbook_no_empty_migrations to
  illustrate.

• [bug] [operations] Repaired ExecuteSQLOp so that it can participate in "diff"
  operations; while this object is typically not present in a reflected
  operation stream, custom hooks may be adding this construct where it needs
  to have the correct to_diff_tuple() method. Pull request courtesy
  Sebastian Bayer.

  References: #1335

• [bug] [typing] Improved the op.execute() method to correctly accept the
  Executable type that is the same which is used in SQLAlchemy
  Connection.execute(). Pull request courtesy Mihail Milushev.

• [bug] [typing] Improve typing of the revision parameter in various command functions.

  References: #930

• [bug] [typing] Properly type the Operations.create_check_constraint.condition
  parameter of Operations.create_check_constraint() to accept boolean
  expressions.

  References: #1266

• [bug] [postgresql] Fixed autogen render issue where expressions inside of indexes for PG need
  to be double-parenthesized, meaning a single parens must be present within
  the generated text() construct.
