AMDGPU: Optimize out implicit kernarg argument allocation if unused
...
We already annotate whether llvm.amdgcn.implicitarg.ptr is known to be
unused. Start using it to avoid allocating the implicit arguments if
unneeded.

[llvm-readobj] Update tests because of changes in llvm-readobj behavior
...
This patch updates tests using llvm-readobj and llvm-readelf, because
soon reading from stdin will be achievable only via a '-' as described
here: https://bugs.llvm.org/show_bug.cgi?id=46400 . Patch with changes to
llvm-readobj behavior is here: https://reviews.llvm.org/D83704

AMDGPU: Remove .value_type from kernel metadata
...
This doesn't appear used for anything, and is emitted incorrectly
based on the description. This also depends on the IR type, and
pointee element type.

[AMDGPU] add support for hostcall buffer pointer as hidden kernel argument
...
Hostcall is a service that allows a kernel to submit requests to the
host using shared buffers, and block until a response is
received. This will eventually replace the shared buffer currently
used for printf, and repurposes the same hidden kernel argument. This
change introduces a new ValueKind in the HSA metadata to represent the
hostcall buffer.
