The C++ frontend generates a broken diagnostic for the following code
snippet since GCC 3.4.0:

=======================
void foo()
{
  if (throw 0)
    ;
}
=======================

bug.cc: In function 'void foo()':
bug.cc:3: error: could not convert 'throw((__cxa_allocate_exception(4u),
#'must_not_throw_expr' not supported by dump_expr#<expression error>),
__cxa_throw(<anonymous>, ((void*)(& _ZTIi)), 0u))' to 'bool'

The "'must_not_throw_expr' not supported by dump_expr" is not implemented,
and the rest of the error message isn't very helpful either.
