Optimize metadata node fields for CHECK-ability While gaining practical experience hand-updating CHECK lines (for moving the new debug info hierarchy into place), I learnt a few things about CHECK-ability of the specialized node assembly output. - The first part of a `CHECK:` is to identify the "right" node (this is especially true if you intend to use the new `CHECK-SAME` feature, since the first CHECK needs to identify the node correctly before you can split the line). - If there's a `tag:`, it should go first. - If there's a `name:`, it should go next (followed by the `linkageName:`, if any). - If there's a `scope:`, it should follow after that. - When a node type supports multiple DW_TAGs, but one is implied by its name and is overwhelmingly more common, the `tag:` field is terribly uninteresting unless it's different. - `MDBasicType` is almost always `DW_TAG_base_type`. - `MDTemplateValueParameter` is almost always `DW_TAG_template_value_parameter`. - Printing `name: ""` doesn't improve CHECK-ability, and there are far more nodes than I realized that are commonly nameless. - There are a few other fields that similarly aren't very interesting when they're empty. This commit updates the `AsmWriter` as suggested above (and makes necessary changes in `LLParser` for round-tripping). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230877 91177308-0d34-0410-b5e6-96231b3b80d8
