gbtozers c52cf11f42 [DebugInfo] Add DIArgList MD to store multple values in DbgVariableIntrinsics ... This patch adds a new metadata node, DIArgList, which contains a list of SSA values. This node is in many ways similar in function to the existing ValueAsMetadata node, with the difference being that it tracks a list instead of a single value. Internally, it uses ValueAsMetadata to track the individual values, but there is also a reasonable amount of DIArgList-specific value-tracking logic on top of that. Similar to ValueAsMetadata, it is a special case in parsing and printing due to the fact that it requires a function state (as it may reference function-local values). This patch should not result in any immediate functional change; it allows for DIArgLists to be parsed and printed, but debug variable intrinsics do not yet recognize them as a valid argument (outside of parsing).
