ubsan: remove CONFIG_UBSAN_OBJECT_SIZE
...
commit 69d0db01e2https://bugzilla.kernel.org/show_bug.cgi?id=214861
With -Warray-bounds almost enabled globally, it doesn't make sense to
keep this around.

lib/test_ubsan.c: VLA no longer used in kernel
...
Since we now build with -Wvla, any use of VLA throws a warning.
Including this test, so... maybe we should just remove the test?
lib/test_ubsan.c: In function 'test_ubsan_vla_bound_not_positive':
lib/test_ubsan.c:48:2: warning: ISO C90 forbids variable length array 'buf' [-Wvla]
For the out-of-bounds test, switch to non-VLA setup.
lib/test_ubsan.c: In function 'test_ubsan_out_of_bounds':
lib/test_ubsan.c:64:2: warning: ISO C90 forbids variable length array 'arr' [-Wvla]

lib/test_ubsan.c: make test_ubsan_misaligned_access() static
...
test_ubsan_misaligned_access() is local to the source and does not need
to be in global scope, so make it static.
Cleans up sparse warning:
lib/test_ubsan.c:91:6: warning: symbol 'test_ubsan_misaligned_access' was not declared. Should it be static?

lib: add testing module for UBSAN
...
This is a test module for UBSAN. It triggers all undefined behaviors
that linux supports now, and detect them.
All test-cases have passed by compiling with gcc-5.5.0.
If use gcc-4.9.x, misaligned, out-of-bounds, object-size-mismatch will not
be detected. Because gcc-4.9.x doesn't support them.
