[PATCH] D77923: OpenCL: Fix some missing predefined macros

[Yaxun Liu via Phabricator via cfe-commits]

LGTM. The objective of the change is to simplify offline compilation. We want to avoid asking users to add -D if a proper macro can be inferred from triple and cpu. Ideally, users only need to specify triple and cpu with clang driver. In case users want to override the default macros for the triple, they can always override them by -D or -U in command line.

The question is whether the default value of the macro is proper. To me this change maintained the old behavior for spir and other targets and the default value seems fine for amdgcn.
