Prevent failure when RowExpr or XmlExpr is parse-analyzed twice. transformExpr() is required to cope with already-transformed expression trees, for various ugly-but-not-quite-worth-cleaning-up reasons. However, some of its newer subroutines hadn't gotten the memo. This accounts for bug #7763 from Norbert Buchmuller: transformRowExpr() was overwriting the previously determined type of a RowExpr during CREATE TABLE LIKE INCLUDING INDEXES. Additional investigation showed that transformXmlExpr had the same kind of problem, but all the other cases seem to be safe.
