- Make sure VarDecls have an associated TypeLoc, like ParamDecls do, then use it for printing the VarDecl's type.
This is done by moving ParamDecl's TypeLoc up to the VarDecl.
This is useful for being able to display the parameter names of function types embedded in VarDecls.
- Use the result TypeLoc of functions for printing. This enables printing parameter names of function types embedded in return types.
- Make sure to annotate attributes while they are printed.
Unless you're familiar with the way the swift source code is organized,
it's not clear what "SourceDocInfo" means, or how it is different from
DocSupport, etc. Move the tests into directories that are named based
on their request (note: we already had one test under CursorInfo, which
just made things even more confusing).
