[PATCH] Fix PR C++/28450 ICE with new of vector and complex types

[Andrew Pinski <pinskia at physics dot uc dot edu>]

We would ICE if someone did a new of either a vector or a complex type
because build_zero_init does not handle these cases.  This fixes the
problem by having build_zero_init handle complex and vector types.

OK? Bootstrapped and tested on i686-linux-gnu with no regressions.

Thanks,
Andrew Pinski

cp/ChangeLog:

	* cp/init.c (build_zero_init): Handle VECTOR_TYPE and
	COMPLEX_TYPEs.

testsuite/ChangeLog:

	* g++.dg/ext/vector4.C
	* g++.dg/ext/complex1.C
