glsl: remove delegating constructors to allow build with C++98 

Delegating constructors is a C++11 feature, so this was breaking when
compiling with C++98. Change the copy_propagation_state() calls that
used the convenience constructor to use a static member function
instead.

Since copy_propagation_state is expected to be heap allocated, this
change is a good fit.
