This replaces all typedefs that define types and not functions by the

This was done mostly automatically using this command:
ag -l '\btypedef\b' src test | xargs -L1 \
perl -i -p0e 's/typedef ([^*;{}]+) (\w+);/using \2 = \1;/sg'
Patchset 2 then adds some manual changes for typedefs for pointer types,
where the regular expression did not match.

Also, if we have different Decompress nodes as inputs, we need to use

This CL changes the existing TorqueError struct into a more general
TorqueMessage by adding a "kind" enum. The contextual for lint errors
is removed and replaced by a list of TorqueMessages.
A MessageBuilder is introduced to help with the different
combinations of present information and method of reporting. A lint
error with custom SourcePosition can be reported like this:
Lint("naming convention error").Position(<src_pos_var>);
While a fatal error, with CurrentSourcePosition can be thrown
like this:
Error("something went horrible wrong").Throw();
This approach is both backwards compatible and should prove flexible
enough to add more information to messages or add other message kinds.
