We will now throw a RangeError in these cases:
* new TypedArray with >= INT32_MAX entries
* new TypedArray whose ArrayBuffer allocation size computation would
cause a 32-bit unsigned overflow.
If we have a function as class extends value, we still cannot assume
that it has a prototype property and that property has a function or
null as its value - blindly calling to_object() on it may fail.
Fixes#5075.
Without this, the oss-fuzz build says:
../Userland/Libraries/LibJS/AST.cpp:58:34: error: member access into incomplete type 'const std::type_info'
return demangle(typeid(*this).name()).substring(4);
