Fix const function-parameter assertion discovered by fuzzer.

During constant-folding, we baked in an assertion stating that any
const-typed variable reference ought to have an initial value, because
you can't declare a const variable without assigning a value. However,
function parameters are an exception to this rule! They are variable
references and are allowed to be const, but will not have an initial
value. (In this case, `const` just means you can't alter the value.)

In this case, all we needed to do was remove the assertion; we already
treated this case defensively and with the appropriate care.
