Matt Arsenault d0799df707 AMDGPU: Stop checking intrinsics not used by HSA for dispatch-ptr 
Only the dispatch.ptr intrinsic is supposed to be used now to get
the workgroup size, and the read.local.size intrinsics do not
work correctly.

Matt Arsenault 3931948bb6 AMDGPU: Add pass to detect used kernel features 
Mark kernels that use certain features that require user
SGPRs to support with kernel attributes. We need to know
before instruction selection begins because it impacts
the kernel calling convention lowering.

For now this only detects the workitem intrinsics.
