dbe42be969 AMDGPU: Annotate implicitarg.ptr usage
We need to pass something to functions for this to work.
It isn't derivable just from the kernarg segment pointer
because the implicit arguments are placed after the
kernel arguments.

Also fixes missing test for the intrinsic.

5472b31175 AMDGPU: Annotate necessity of flat-scratch-init
As an approximation of the existing handling to avoid
regressions. Fixes using too many registers with calls
on subtargets with the SGPR allocation bug.

bcb8abee35 AMDGPU: Annotate features from x work item/group IDs.
This wasn't necessary before since they are always enabled
for kernels, but this is necessary if they need to be
forwarded to a callable function.

f9915c27c2 AMDGPU: Detect kernarg segment pointer
This is necessary to pass the kernarg segment pointer
to callee functions. Also don't unconditionally enable
for kernels.

a20c1d0cec AMDGPU: Annotate call graph with used features
Previously this wouldn't detect used features indirectly
used in callee functions.
