JDK-8305590 removes `-fcheck-new` when building with gcc. It turns out Visual Studio has a similar option, though inverted in behavior and default.

It seems like /Zc:throwingNew- (the default) corresponds to gcc -fcheck-new, and /Zc:throwingNew corresponds to -fno-check-new (the default).

The Visual Studio documentation strongly recommends using /Zc:throwingNew if possible, as turning it off (the default) seriously bloats code and inhibits optimizations.

As mentioned in JDK-8305590, the standard says that an allocation function can report allocation failure either by returning null (when it must have a nothrow exception specification), or by throwing `std::bad_alloc` (so obviously must not be declared as non-throwing). HotSpot allocation functions terminate the program instead of throwing on allocation failure, so similarly don't need the result checked for null.

The documentation for /Zc:throwingNew is somewhat vague and confusing, so some investigation is probably needed to verify it really has the desired effect for us.
