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.
