* module/language/tree-il/optimize.scm (peval): The old approach of
optimistically producing constants and then de-constifying them at
their uses was not only cumbersome but incorrect: it both failed to
preserve identity in some cases and failed to retain immutable
constant values. Instead, now we only produce constants if they
really are constant and immutable. The constant folder has to have a
few more algebraic cases to be as effective as it was, to destructure
(car (cons _ _)) appropriately. On the plus side, now constructors
and deconstructors can handle impure cases more generally.
* test-suite/tests/tree-il.test ("partial evaluation"): Add constructor
and destructuring tests. Adapt other tests to new expectations.
