spanner/spansql: don't coalesce adjacent comments with intervening tokens

Comments on adjacent lines should only form a single comment block if
there aren't other tokens in between. This prevents inline comments from
being joined in a situation such as
	CREATE TABLE Foo (
		F1 INT64, -- some comment
		F2 INT64, -- another comment
	) PRIMARY KEY (F1);

This actually simplifies the parsing by doing the comment collapsing in
skipSpace instead of trying to reverse-engineer it after the parse
completes.
