[Bug c++/16529] New: namespace-alias shall no be declared as the name of any other entity

[boris at kolpackov dot net]

According to 7.3.2/4 

"A namespace-name or namespace-alias shall not be declared as the name of any
other entity in the same declarative region. A namespace-name defined at global
scope shall not be declared as the name of any other entity in any global scope
of the program. No diagnostic is required for a violation of this rule by
declarations in different translation units."

the following c++ is ill-formed:

namespace m
{
}

namespace n
{
  namespace m
  {
  }
}

namespace m = n::m;
