Subject: [PATCH] * [HIPIFY] [FIX] Replacement error: enum cudaMemcpyKind kind
 -> hipMemcpyKindyKind kind

https://github.com/GPUOpen-ProfessionalCompute-Tools/HIP/issues/72

[Solution] [Workaround]
Offset calculation for enum VarDecl as param decl, declared with enum type specifier.

[Result]
enum cudaMemcpyKind kind -> enum hipMemcpyKind kind

[ToDo]
Test on terminal qualifiers (const, etc).
