Subject: Revert "Remove MacroStmts as per edwin0cheng" (cc @edwin0cheng) and
 add a fixme to document it.

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.
