[Development] Updating x86 SIMD support in Qt

[Jean-Michaël Celerier]

Re. wasm, as far as I know it's 32-bit (not x86 at all) but with a
compatibility layer provided by emscripten
which allows sse & avx intrinsincs to be translated to either equivalent
vector instructions in the wasm bytecode,
or shims which do it manually.

Cheers,
