  1. Support multiple declarations in a single statement 

    A new statement node called `DeclStmtNode` has been introduced to hold
multiple declarations. The AST nodes backed by non-terminals that take
`decl` now accept a `DeclStmtNode` instead of a `DeclNode`. These nodes
include `LoopInitNode` and `CompoundStmtNode`; other nodes remain
unaffected.
Since `DeclStmtNode` is simply a sequence of `DeclNode`s, the `Visit`
functions will visit each `DeclNode` it holds.

  2. Fix use-after-move 

    Objects are placed in a valid but unspecified state after being
moved-from.

  3. Inline type alias & rename data member 

    Since an item of a compound statement is no longer an `std::variant`, we
no longer use a type alias to simplify the type. Additionally, the data
member has been renamed to remove the word `item`, which is a technical
term used during parsing.
