5d45e0b69a C++: block recursion when parsing subsequent case statements.
A case or a default statement must be followed by another statement.
When a such a case (or default) statement is followed immediately by
another case (or default) statement, then this would create a linked
list, and the parser will recurse to parse such input.

In order to prevent the parser running out of stack space while
recursing, parse this corner case by blocking parsing a labeled
statement as the first statement after a labeled statement.

The advantage is that these statements do not form a linked list, so any
subsequent visitation of the AST won't run out of stack space either.

c56b999fff C: Parser: Support parsing of c99 designated initializers
In case:

    int a[6] = { [4] = 29, [2] = 15 };
    struct point { int x, y; };
    struct point p = { .y = 3, .x = 2 };

Grammar change when c99 language feature is enabled:
old grammar:

    braced-init-list :: '{' initializer-list '}'

new grammar:

    braced-init-list :: '{' designated-initializer-list '}'
    designated-initializer-list :: designated-initializer (',' designated-initializer )*
    designated-initializer :: designator* initializer-clause
    designator :: '.' identifier
                | '[' constant-expression ']'
