This patch doesn't ship all features of ES2015 variable/scoping
changes, notably omitting the removal of legacy const. I think
function hoisting, let and class in sloppy mode can stand to
themselves as a package, and the legacy const change is much
riskier and more likely to be reverted, so my intention is to
pursue those as a separate, follow-on patch.

Reapply r8783 with an additional fix.
Because the preparser and parser do not use the same scope analysis to
determine if a function can be lazily compiled, the parser can have false
positives. Rather than treating this as a parse error, treat the preparser
as authoritative and eagerly compile the function.
