Fix parsing of variable declarations directly after a class / struct.

Previous indent:
class A {
}
a;
void f() {
};

With this patch:
class A {
} a;
void f() {
}
;

The patch introduces a production for classes and structs, and parses
the rest of the line to the semicolon after the class scope.
This allowed us to remove a long-standing wart in the parser that would
just much the semicolon after any block.
Due to this suboptimal formating some tests were broken.

Some unrelated formatting tests broke; those hit a bug in the ast
printing, and need to be fixed separately.
