Doesn't look like a C++ front-end issue.

The problem with this testcase is that set_decl_tls_model adds A<T>::b, an
uninstantiated template, to the symbol table. This ICE was introduced by
honza's r211689.
I'll deal with the other testcase.

Fixed for 4.9.2. Still broken on trunk because of the set_decl_tls_model
issue, which I will leave to honza.
