Sam McCall aef37d43d7 c/c++ highlighting: various tweaks
- treat `restrict`/`_Atomic` like `const`/`volatile` => @keyword.storage.modifier
- highlight `unsigned int` as builtin => @type.builtin
- recognize `static_cast` and friends => @keyword
- `template` is a kind of entity like `typename` => @keyword.storage.type
- many declaration modifiers have nothing to do with storage/types
  (explicit, friend, access specifiers, inline in C++) => @keyword
- fix floats highlighted as integer => @constant.numeric
