[PATCH] D102067: [amdgpu-arch] Guard hsa.h with __has_include

[Jon Chesterfield via Phabricator via cfe-commits]

JonChesterfield added a comment.

A thought - we need to keep return 0 for success, but could return a different integer for each failure mode. That would be useful when guessing why it failed. Orthogonal to this patch.
