c++: mangling union{1} in template [PR104847]

My implementation of union non-type template arguments in r11-2016 broke
braced casts of union type, because they are still in syntactic (undigested)
form.

PR c++/104847

gcc/cp/ChangeLog:

* mangle.cc (write_expression): Don't write a union designator when
undigested.

gcc/testsuite/ChangeLog:

* g++.dg/abi/mangle-union1.C: New test.
