Aakanksha Patil c56d2afc63 AMDGPU: Handle "uniform-work-group-size" attribute (fix for RADV)
A previous patch for "uniform-work-group-size" attribute was found to break
some RADV and possibly radeon SI tests and had to be retracted.
This patch fixes that.

Aakanksha Patil bc568766b2 Revert r348971: [AMDGPU] Support for "uniform-work-group-size" attribute
This patch breaks RADV (and probably RadeonSI as well)

Aakanksha Patil 729309cc89 [AMDGPU] Support for "uniform-work-group-size" attribute
Updated the annotate-kernel-features pass to support the propagation of uniform-work-group attribute from the kernel to the called functions. Once this pass is run, all kernels, even the ones which initially did not have the attribute, will be able to indicate weather or not they have uniform work group size depending on the value of the attribute.

Matt Arsenault 9166ce86e8 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.

Matt Arsenault 254ad3de5c 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.

Matt Arsenault e15855d9e3 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.

Matt Arsenault 23e4df6a59 AMDGPU: Detect kernarg segment pointer
This is necessary to pass the kernarg segment pointer
to callee functions. Also don't unconditionally enable
for kernels.

Matt Arsenault 6b93046f29 AMDGPU: Annotate call graph with used features
Previously this wouldn't detect used features indirectly
used in callee functions.
