flag from clang, and disable zero-base shadow support on all platforms where it is not the default behavior. - It is completely unused, as far as we know. - It is ABI-incompatible with non-zero-base shadow, which means all objects in a process must be built with the same setting. Failing to do so results in a segmentation fault at runtime. - It introduces a backward dependency of compiler-rt on user code, which is uncommon and complicates testing. This is the LLVM part of a larger change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199371 91177308-0d34-0410-b5e6-96231b3b80d8
