commit 4644f6fdf12854ac8f5927460d39645318c40e6a
Author: Jeremy Roman <jbroman@chromium.org>

Bindings: Prevent dictionary value local variable from colliding with C++ keywords.

Using |cpp_value| was considered, but since it's possible for this to be the
same between two members (using ImplementedAs=), this seemed slightly confusing
when reading the generated source.

Instead, following the V8 representation of the value, {{member.name}}Value,
the C++ value has been named {{member.name}}CppValue.
