In some contexts, including the motivating case of determining whether the expressions that define the shape of a variable are "constant expressions" in the sense of the Fortran standard, expression rewriting via Fold() is not necessary, and should not be required. The inquiry intrinsics LBOUND, UBOUND, and SIZE work correctly now in specification expressions and are classified correctly as being constant expressions (or not). Getting this right led to a fair amount of API clean-up as a consequence, including the folding of shapes and TypeAndShape objects, and new APIs for shapes that do not fold for those cases where folding isn't needed. Further, the symbol-testing predicate APIs in Evaluate/tools.h now all resolve any associations of their symbols and work transparently on use-, host-, and construct-association symbols; the tools used to resolve those associations have been defined and documented more precisely, and their clients adjusted as needed.
