kasan: add compiler support for clang
Patch series "kasan: support alloca, LLVM", v4.
This patch (of 5):
For now we can hard-code ASAN ABI level 5, since historical clang builds
can't build the kernel anyway. We also need to emulate gcc's
__SANITIZE_ADDRESS__ flag, or memset() calls won't be instrumented.
