Yes, although the specific problem is they are printed. We don't have meaningful sections in the text format.

Probably, but that would still require a new custom MCAsmStreamer subclass. Essentially all we want out of the MCStreamer is what MCBasicAsmStreamer has in it. Essentially anything other than printing instructions and labels are going to be incorrect.

This was one of the first things I tried and it doesn't work. WebAssembly does current print .text / .data directives.
