Fix printing of types in initializers with suppressed tags.
Tag and specifier printing can be suppressed in Decl::printGroup, but these suppressions leak into the initializers. Thus
int *x = ((void *)0), *y = ((void *)0);
gets printed as
int *x = ((void *)0), *y = ((*)0);
And
struct { struct Z z; } z = {(struct Z){}};
gets printed as
struct { struct Z z; } z = {(){}};
The stops the suppressions from leaking into the initializers.
