No, I don't know. According to 
https://github.com/emscripten-core/emscripten/pull/9299#discussion_r316893349 
`#pragma once` is the convention in Emscripten's header files, but I don't know 
what the trade offs are. @sbc100 do you have a better answer for this?

I agree. These have been around since the beginning of the file and we just 
kept adding them for consistency and never did anything else with them. I'll 
remove them now, but in the future (once the proposal is standardized?) we 
should put actual doc comments in their place, like xmmintrin.h has.
