Auto merge of #39990 - CryZe:emscripten-no-vectorization, r=alexcrichton
Turn off Vectorization for Emscripten When targeting Emscripten, rustc emits Vector Instructions by default. However Web Assembly doesn't support Vector Instructions yet, which causes Binaryen to fail converting the intermediate asm.js code to Web Assembly. While asm.js kind of supports Vector Instructions, they aren't supported by any browser other than Firefox, often meaning that they need to be emulated very slowly. So it should just be turned off for all Emscripten targets. Fixes #38558
