    gccrs: Scaffolding HIRFullVisitor for inline asm
    
    gcc/rust/ChangeLog:
    
            * ast/rust-ast-visitor.h:
            Scaffolding HIRFullVisitor for inline asm
            * ast/rust-ast.cc (InlineAsm::accept_vis): Likewise.
            * hir/tree/rust-hir-visitor.h (RUST_HIR_VISITOR_H): Likewise.
            * hir/tree/rust-hir.cc (InlineAsm::accept_vis): Likewise.
