[lldb] Pass -fno-objc-exceptions for objcxx targets

JDevlieghere · JDevlieghere · commit fa95e3559335 · 2020-09-02T21:59:48.000-07:00
When compiling an Objective-C++ file, __has_feature(cxx_exceptions) will
return true with -fno-exceptions but without -fno-objc-exceptions. This
was causing LLVM_ENABLE_EXCEPTIONS to be defined for a subset of files.
