Yaxun Liu 26f7566ff8 Re-commit [OpenCL] AMDGCN: Fix size_t type 
There was a premature cast to pointer type in emitPointerArithmetic which caused assertion in tests with assertion enabled.

Yaxun Liu 6305f8a351 [OpenCL] AMDGCN: Fix size_t type 
Pointers of certain GPUs in AMDGCN target in private address space is 32 bit but pointers in other address spaces are 64 bit. size_t type should be defined as 64 bit for these GPUs so that it could hold pointers in all address spaces. Also fixed issues in pointer arithmetic codegen by using pointer specific intptr type.
