Now that we consistently preparse the parameters of a preparsed
function, these no longer crash.

If an inner function only declares a variable but doesn't use it, Parser
and PreParser produced different unresolved variables, and that confused
the pessimistic context allocation.
This is continuation to https://codereview.chromium.org/2388183003/
This CL fixes more complicated declarations (which are not just one
identifier). For this, PreParser needs to accumulate identifiers used
in expressions.
In addition, this CL manifests FLAG_lazy_inner_functions in tests, so that
we get clusterfuzz coverage for it.

This would've caught the "preparser tracking only unresolved variables
but no declarations is not enough" bug.
