Clean up a few failures to set collation fields in expression nodes.

Browse Source 
I'm not sure these have any non-cosmetic implications, but I'm not sure
they don't, either.  In particular, ensure the CaseTestExpr generated
by transformAssignmentIndirection to represent the base target column
carries the correct collation, because parse_collate.c won't fix that.
Tweak lsyscache.c API so that we can get the appropriate collation
without an extra syscache lookup.
