i965: Make vec4_visitor's destructor virtual
We need a virtual destructor when at least one of the class' methods is virtual.
Failure to do so might lead to undefined behavior when destructing derived classes.
Fixes the following warning:
brw_vec4_gs_visitor.cpp: In function 'const unsigned int* brw::brw_gs_emit(brw_context*, gl_shader_program*, brw_gs_compile*, void*, unsigned int*)':
brw_vec4_gs_visitor.cpp:703:11: warning: deleting object of polymorphic class type 'brw::vec4_gs_visitor' which has non-virtual destructor might cause undefined behaviour [-Wdelete-non-virtual-dtor]
delete gs;
Curro: This shouldn't be causing any actual bugs at the moment because
gen6_gs_visitor is the only subclass of vec4_visitor destroyed through
a pointer of a base class (vec4_gs_visitor *) and its destructor is
basically the same as its parent's. Anyway it seems sensible to change
this so it doesn't bite us in the future.
