Gracefully handle guard-page mmap failures in OSAllocatorPOSIX
https://bugs.webkit.org/show_bug.cgi?id=279155
rdar://135306076
Reviewed by Yusuke Suzuki.
While it's unlikely that these mmap calls fail, it is still possible --
e.g. if the process hits the maximum number of allocations midway
through this call. This patch makes it so that we won't just ignore such
failures, and will instead clean up + tell the caller that their
allocation failed.
