__builtin_popcount and __builtin_popcountll are builtin functions provided by Clang and GCC, but MSVC doesn't provide the same function. Instead, __popcnt and __popcnt64 should be used when building WebKit for Windows. https://learn.microsoft.com/en-us/cpp/intrinsics/popcnt16-popcnt-popcnt64?view=msvc-170
