Remove CXXRecordDecl printer FIXME (#175397)
It suggested it would be better to print attributes before the decl
kind, to be consistent with value declarations.
But attributes are not accepted by the language before the decl kind:
[[deprecated]] class A;
__attribute__((deprecated)) class A;
__declspec(deprecated) class A;
are all invalid or ignored. The only way to put an attribute before the
decl kind is with something like:
[[deprecated]] struct A {} a;
But that declares a variable, not a record tyoe, and will be correctly
handled by the variable decl printer.
