Janusz Majnert 5a04c5cea2 Make torque emit structs in classes in order 
Torque compiler emits a C++ class definition header
class-definitions-tq.h. Unfortunately it does so in a manner that
introduces randomness into the ordering of some structs. This means that
every full build of V8 may yield a different header.
Since this header is included in a lot of files in V8, it causes a lot
of ccache misses (over a 1000).

This commit makes sure that the structs are emitted in lexical order.
