  Changed paths:

    M mlir/test/lib/Dialect/Test/TestDialect.cpp

  Log Message:
  -----------
  [mlir][bytecode] Fix dialect version parsing.

We were querying the wrong EncReader along some paths that resulted in
failures depending on if one encountered an Attribute from an unloaded
dialect before encountering an operation from that dialect.

Also fix error where we were able to emit "custom" form for an attribute
without custom form in TestDialect.
