JPEG-XL and upgrading MinGW GCC

[L. E. Segovia]

Hi Halla,

It's a problem because Highway doesn't even have a way to control 
intrinsics-- if it detects x86, it'll build the whole batch.

In this case, GCC 7.3 cannot reinterpret_cast between a vector of floats 
and a matching-size vector of doubles without intrinsics and SIMD types; 
the library uses aligned arrays for its vectors. GCC 11.2 (and, fwiw, 
Clang and MSVC) deal with this without a hitch.
