But why do you need this (at least for OMP_CLAUSE_COLLAPSE)?
The OMP_CLAUSE_COLLAPSE (and OMP_CLAUSE_ORDERED if not NULL) argument
is required to be INTEGER_CST already during parsing, it can't be even
template argument etc. (because we need that number already during parsing
to find out how many nested loops to parse specially).
So I don't see how would the last argument to tsubst_expr make any
difference there.
Oh, I'd not realized it couldn't be a template argument. (the same is not true
of tile parameters).
