Subject: [OPENMP] Codegen for threadprivate variables For all threadprivate
 variables which have constructor/destructor emit call to void
 __kmpc_threadprivate_register(ident_t * <Current Location>, void *<Original
 Global Addr>, kmpc_ctor <Constructor>, kmpc_cctor NULL, kmpc_dtor
 <Destructor>); In expressions all references to such variables are replaced
 by calls to void *__kmpc_threadprivate_cached(ident_t *<Current Location>,
 kmp_int32 <Current Thread Id>, void *<Original Global Addr>, size_t <Size of
 Data>, void ***<Pointer to autogenerated cache – array of private copies of
 threadprivate variable>); Test test/OpenMP/threadprivate_codegen.cpp checks
 that codegen is correct. Also it checks that codegen is correct after
 serialization/deserialization and one of passes verifies debug info.
