[PATCH] D26157: [OpenCL] always use SPIR address spaces for kernel_arg_addr_space MD

[Yaxun Liu via cfe-commits]

yaxunl added a comment.

One purpose of kernel arg info metadata is to be passed to OpenCL runtime to fulfill clGetKernelArgInfo queries. (https://www.khronos.org/registry/cl/sdk/1.2/docs/man/xhtml/clGetKernelArgInfo.html). As such, the address space id needs to be at source level instead of IR level.
