  "message": "sem: Add CompoundStatement\n\nThis change introduces sem::CompoundStatement, a new base class for\nstatements that can hold other statements.\n\nsem::BlockStatements now derives from sem::CompoundStatement, and\nthis change introduces the following new CompoundStatements:\n* `sem::IfStatement`\n* `sem::ElseStatement`\n* `sem::ForLoopStatement`\n* `sem::LoopStatement`\n* `sem::SwitchStatement`.\nThese new CompoundStatements are now inserted into the semantic\ntree as now documented in `docs/compound_statements.md`.\n\nThe `sem::BlockStatement::FindFirstParent()` methods have been\nmoved down to `sem::Statement`.\n\nThe `Resolver::BlockScope()` method has been replaced with\n`Resolver::Scope()` which now maintains the `current_statement_`,\n`current_compound_statement_ ` and `current_block_`. This\nsimplifies statement nesting.\n\nThe most significant change in behavior is that statements now\nalways have a parent, so calling Block() on the initializer or\ncontinuing of a for-loop statement will now return the\nBlockStatement that holds the for-loop. Before this would\nreturn nullptr.\n\nFixed: tint:979\nChange-Id: I90e38fd719da2a281ed9210e975ab96171cb6842\nReviewed-on: https://dawn-review.googlesource.com/c/tint/+/57707\nKokoro: Kokoro \u003cnoreply+kokoro@google.com\u003e\nCommit-Queue: Ben Clayton \u003cbclayton@google.com\u003e\nReviewed-by: James Price \u003cjrprice@google.com\u003e\n",
