Boris Zbarsky d36e5a4ea5 Bug 1214364 part 4. Only output full-featured Init methods for dictionaries that need them. r=peterv
Dictionaries that we never initialize with JS values don't need a full-featured
Init() method.  Instead, we output a cut-down Init() method that doesn't even
take a JSContext and Value as argument, and skips as much work as it can.  It
uses constant-false for "is the value present?", but also, to avoid compilation
errors due to use of `cx` and `val` in now-dead conversion code, it tells the
native-to-JS conversion machinery that the value is always missing, which lets
it skip most of the the work it would normally try to do and just output
initialization to the default value.  We only need to do this for members that
have default values; the others either remain no-passed or are required members
with no default-initialization behavior.

This saves about 330KB of codesize on Linux64 without PGO and 285KB with PGO.
