[mlir][irdl] Fix crash in TypeOp/AttributeOp verify on empty sym_name (#184598) TypeOp::verify() and AttributeOp::verify() called StringRef::front() to check for leading '\!' or '#' sigils before passing the name to isValidName(). When sym_name is empty, front() triggers an assertion failure: Assertion `\!empty()' failed. Fix: guard the front() calls with an emptiness check. An empty sym_name then falls through to isValidName(), which already emits a proper diagnostic: error: name of type is empty Fixes #159949
