[PATCH] [WebAssembly] Skeleton WebAssembly target

[Rafael Espíndola]

I am really happy to see this!

I just tried to build it with cmake and got some errors:

WebAssemblyInstPrinter.cpp:28:10: fatal error:
'WebAssemblyGenAsmWriter.inc' file not found
WebAssemblyISelDAGToDAG.cpp:60:10: fatal error:
'WebAssemblyGenDAGISel.inc' file not found

Do code models and relocation models have any meaning in webassembly?

Is SIMD an optional feature?

Atomics? Is there a memory model? You mentioned that there is nothing
like C's undefined behavior...

It is a bit funny that webassembly is an OS. Targeting web assembly
always implies the same apis, no?

Cheers,
Rafael
