HS: hs-strip-order-deep + dict equality in assert-equal (+1 test)

hs-make-object appends _order for consistent key iteration (needed by
repeat-in loops). But assert-equal (equal?) sees _order as a real key,
breaking arrayLiteral "arrays containing objects work".

Add hs-strip-order-deep to runtime.sx that recursively strips _order
from dicts. Update emit_eval in the generator to wrap deep-dict evals
with hs-strip-order-deep so assert-equal comparisons ignore _order.
