- On Android, we were already doing it, but using fallible allocations.
- On *nix, it probably doesn't make a difference, but can't hurt. For
most things in Gecko, operator new/delete are inlined and thus
replaced by direct calls to the underlying allocator functions
(moz_xmalloc, malloc, etc.). This may have a benefit for some third
party libraries that would otherwise go through libstdc++'s to
eventually end up back into our allocator via the zone allocator
on macOS and via the exported symbols on others.
- On Windows, because of how some CRT static libraries are, a non-inlined
operator new (thanks to some disabled STL wrapping) would end up linked
against the system malloc, causing problems.
Overall, this can only be better. This also reduces the number of places
where we define those functions.
And on Android, this means operator new within mozglue becomes infallible,
which is more consistent with everything else.
