Subject: [PATCH 1/5] [AMDGPU] Introduce GFX9/10.1/10.3/11 Generic Targets
These generic targets include multiple GPUs and will, in the future, provide a way to build once and run on multiple GPU, at the cost of less optimization opportunities.
Note that this is just doing the compiler side of things, device libs an runtimes/loader/etc. don't know about these targets yet, so none of them actually work in practice right now. This is just the initial commit to make LLVM aware of them.
No docs in this patch either as I plan to do it all in a follow-up patch.

+Generic processors allow execution of a single code object on any of the processors that
it supports. Such code objects may not perform as well as those for the non-generic processors.
Generic processors are only available on code object V6 and above (see :ref:`amdgpu-elf-code-object`).
-Generic processor code objects are versioned (see :ref:`amdgpu-elf-header-e_flags-table-v6-onwards`).
-The version number is used by runtimes to determine if a code object can be run on a specific agent.
-The version number may be increased as-needed, e.g., when a major codegen change occurs for a generic
-target.
+Generic processor code objects are versioned (see :ref:`amdgpu-elf-header-e_flags-table-v6-onwards`) between 1 and 255.
+The version of non-generic code objects is always set to 0.
+
+For a generic code object, adding a new supported processor may require the code generated for the generic target to be changed
+so it can continue to execute on the previously supported processors as well as on the new one.
+When this happens, the generic code object version number is incremented at the same time as the generic target is updated.
+
+Each supported processor of a generic target is mapped to the version it was introduced in.
+A generic code object can execute on a supported processor if the version of the code object being loaded is
+greater than or equal to the version in which the processor was added to the generic target.
