test_overflow: Add memory allocation overflow tests
Make sure that the memory allocators are behaving as expected in the face
of overflows of multiplied arguments or when using the array_size()-family
helpers.
Example output of new tests (with the expected __alloc_pages_slowpath
and vmalloc warnings about refusing giant allocations removed):
[ 93.062076] test_overflow: kmalloc detected saturation
[ 93.062988] test_overflow: kmalloc_node detected saturation
[ 93.063818] test_overflow: kzalloc detected saturation
[ 93.064539] test_overflow: kzalloc_node detected saturation
[ 93.120386] test_overflow: kvmalloc detected saturation
[ 93.143458] test_overflow: kvmalloc_node detected saturation
[ 93.166861] test_overflow: kvzalloc detected saturation
[ 93.189924] test_overflow: kvzalloc_node detected saturation
[ 93.221671] test_overflow: vmalloc detected saturation

[ 93.296217] test_overflow: all tests passed
