Zachary, Todd, you added these in http://reviews.llvm.org/D3929. I know it's a 
long time, but do you recall what was the original motivation for that?

In light of the issue in http://reviews.llvm.org/D20671, I've experimenting 
with compiling lldb with exceptions enabled, and this code here is interfering 
with the standard llvm logic for enabling them (LLVM_ENABLE_EH). Enabling this 
should not make any difference in the common case, as llvm already adds one set 
of exception-disabling flags if you don't specify the flag I mentioned 
(llvm/cmake/modules/AddLLVM.cmake).

So, unless we know of a concrete use case where this is needed, I think we 
should remove it.
