SystemStats::hasNeon missing init

[otristan]

See

SystemStats::hasNeon on iOS/macOS

I think adding the following to CPUInformation::initialise() should mark hasNeon for macOS (DTK) and iOS. I have not tested it on hardware though, so it would be useful if anyone could? #ifdef JUCE_ARM { unsigned int neon = 0; size_t len = sizeof (neon); if (sysctlbyname ("hw.optional.neon", &neon, &len, nullptr, 0) >= 0) hasNeon = neon != 0; } #endif
