Subject: [PATCH] Support multiple __label__ declarations

Support multiple __label__ declarations at the beginning of a block
as long as they're contiguous.

gcc and clang accept:
    { __label__ a,b; __label__ c;  /*...*/ }
.
Tcc would fail it. This patch makes it accept it.

The patch:
-        if (tok == TOK_LABEL) {
+        while (tok == TOK_LABEL) {
