very simple semantic analysis that just builds the AST; minor changes for lexer to pick up source locations I didn't think about before. Comments AST is modelled along the ideas of HTML AST: block and inline content. * Block content is a paragraph or a command that has a paragraph as an argument or verbatim command. * Inline content is placed within some block. Inline content includes plain text, inline commands and HTML as tag soup. llvm-svn: 159790
