This reverts commit 7a49165f5d5c8186edd04f874eae8a98e39d3df6. MacroStmts ast node is not used by itself, but it pertains to SyntaxNodeKind MACRO_STMTS that is used by ra_paser, so even tho the node itself is not used, it is better to keep it with a FIXME to actually add a doc comment when it becomes useful.
