    gccrs: Handle IfLetExprConseqElse in DefaultResolver
    
    This relies on the DefaultASTVisitor visitor for IfLetExprConseqElse
    performing a virtual call of the visitor for IfLetExpr, which doesn't
    hold when DefaultASTVisitor is generated by the X-macro-DSL-system I
    have in another patch.
    
    gcc/rust/ChangeLog:
    
            * resolve/rust-default-resolver.cc (DefaultResolver::visit): Add
            visitor for IfLetExprConseqElse.
            * resolve/rust-default-resolver.h (DefaultResolver::visit):
            Likewise.
