[clangd] targetDecl() returns only NamedDecls.

Authored by sammccall on Fri, Jan 3, 8:34 AM.



While it's perfectly reasonable for non-named decls such as
static_assert to resolve to themselves:

  • nothing else ever resolves to them
  • features based on references (hover, highlight, find refs etc) tend to be uninteresting where only trivial references are possible
  • returning NamedDecl is a more convenient API (we cast to it in many places)
  • this aligns closer to findExplicitReferences/explicitReferenceTargets

This fixes a crash in explicitReferenceTargets: if the target is a
non-named decl then there's an invalid unchecked cast to NamedDecl.

In practice this means when hovering over e.g. a static_assert:

  • before ac3f9e4842, we would show a (boring) hover card
  • after ac3f9e4842, we would crash
  • after this patch, we will show nothing
