Alex Shlyapnikov f3cc7cc3d8 [Sanitizers] 32 bit allocator respects allocator_may_return_null flag 
Summary:
Make SizeClassAllocator32 return nullptr when it encounters OOM, which
allows the entire sanitizer's allocator to follow allocator_may_return_null=1
policy, even for small allocations (LargeMmapAllocator is already fixed
by D34243).

Will add a test for OOM in primary allocator later, when
SizeClassAllocator64 can gracefully handle OOM too.
