1ddffe9f - HIP: add byte permute fallback when __builtin_amdgcn_perm is unavailable (#30915)

HIP: add byte permute fallback when __builtin_amdgcn_perm is unavailable (#30915) * HIP: add byte permute fallback when __builtin_amdgcn_perm is unavailable amdgcnspirv rejects target-specific builtins unless they are guarded by `__builtin_amdgcn_is_invocable`, so 66 of 145 HIP files failed to build Wrap the perm calls in a helper that keeps v_perm_b32 when the target has it and falls back to a portable byte select otherwise * move perm helper to vendors/hip.h
