Argyrios Kyrtzidis 478276271b [index] Update indexing to handle CXXDeductionGuideDecls properly 
CXXDeductionGuideDecls can't be referenced so there's no need to output a symbol occurrence for them.
Also handle DeducedTemplateSpecializationTypeLocs in the TypeIndexer so we don't miss the symbol occurrences of the corresponding template decls.

Krasimir Georgiev e62dd8b5e9 [Index] Prevent canonical decl becoming nullptr 
Summary:
This patch prevents getCanonicalDecl returning nullptr in case it finds
a canonical TemplateDeclaration with no attached TemplatedDecl.
Found by running the indexer over a version of the standard library deep inside
a template metaprogramming mess.

Ben Langmuir da467ed444 [index] Don't add relation to a NamedDecl with no name 
Unless it's one of the special cases (tag, category) that we can handle.
This syncs up the check between handling a decl and handling a relation.

This would cause invalid nameless decls to end up in relations despite
having no name or USR.

Ben Langmuir 6aed6b4f01 [index] Index system ImportDecls even when there is a DeclarationsOnly filter 
Whether we call an ImportDecl a decl or a reference symbol role is
somewhat academic, but in practice it's more like a declaration because
it is interesting even to consumers who wouldn't care about references.
Most importantly, we want to report the module dependencies of system
modules even when we have declaration-only filtering.
