Validate allocations against mappings
Bug 120032857 is seeing what appears to be allocations with incorrect
end addresses, leading to a much later crash when it tries to map
a zero page outside the valid virtual address space. Detect allocations
that extend outside the highest or lowest memory mapping and crash
immediately instead.
