JF Bastien 1d20a5e9e8 WebAssembly: update syntax
Summary:
Follow the same syntax as for the spec repo. Both have evolved slightly
independently and need to converge again.

This, along with wasmate changes, allows me to do the following:

  echo "int add(int a, int b) { return a + b; }" > add.c
  ./out/bin/clang -O2 -S --target=wasm32-unknown-unknown add.c -o add.wack
  ./experimental/prototype-wasmate/wasmate.py add.wack > add.wast
  ./sexpr-wasm-prototype/out/sexpr-wasm add.wast -o add.wasm
  ./sexpr-wasm-prototype/third_party/v8-native-prototype/v8/v8/out/Release/d8 -e "print(WASM.instantiateModule(readbuffer('add.wasm'), {print:print}).add(42, 1337));"

As you'd expect, the d8 shell prints out the right value.

Dan Gohman e51c058ecc [WebAssembly] Switch to a more traditional assembly syntax
This new syntax is built around putting each instruction on its own line
in a "mnemonic op, op, op" like syntax. It also uses conventional data
section directives like ".byte" and so on rather than requiring everything
to be in hierarchical S-expression format. This is a more natural syntax
for a ".s" file format from the perspective of LLVM MC and related tools,
while remaining easy to translate into other forms as needed.
