This commit is a precursor to making lazy arrow function parsing use
similar logic to function(){} argument parsing.
Originally landed in these three CLs:
https://codereview.chromium.org/1078093002
https://codereview.chromium.org/1083623002
https://codereview.chromium.org/1083953002
These were rolled out due to a performance regression on CodeLoad. This
patchset will fix that by avoiding creation of a DuplicateFinder in the
full parser.
