commit 69d0db01e2 upstream.
The object-size sanitizer is redundant to -Warray-bounds, and
inappropriately performs its checks at run-time when all information
needed for the evaluation is available at compile-time, making it quite
difficult to use:
https://bugzilla.kernel.org/show_bug.cgi?id=214861
With -Warray-bounds almost enabled globally, it doesn't make sense to
keep this around.
