maybe_constant_value may return a constant, but that doesn't mean that

maybe_constant_value may return a constant, but that doesn't mean that
outer_nelts was already constant; if

This is a patch for two C++ bugs:
67913 - new expression with negative size not diagnosed
67927 - array new expression with excessive number of elements
not diagnosed
The C++ front end rejects a subset of array declarators with negative
bounds or with bounds in excess of some
