This patch adds initial support for codegen of private and firstprivate clauses of nvptx.
I simply use the same support in host codegeneration, even though optimizations are possible.
Optimizations may be done by having codegen first analyze data sharing attributes on target and teams (e.g. target firstprivate and teams private on the same variable can drop firstprivate on target). These optimizations will be subject of a successive patch.
