When -DORC_RT_ENABLE_EXCEPTIONS=On and -DORC_RT_ENABLE_RTTI=On are passed we need to ensure that the resulting compiler flags (e.g. -fexceptions, -frtti for clang/GCC) are appended so that we override any inherited options (e.g. -fno-exceptions, -fno-rtti) from LLVM. Updates unit tests to ensure that these compiler options are applied to them too.

We could instead use the CXX_RTTI and CXX_EXCEPTIONS properties here, and do the checks here instead of inside the the header. This is more akin to how a library consumer would compile the orc-rt.
These are cross platform and will work on windows (but we don't have that supported yet)

set_target_properties(CoreTests PROPERTIES
CXX_RTTI ${ORC_RT_ENABLE_RTTI}
CXX_EXCEPTIONS ${ORC_RT_ENABLE_EXCEPTIONS}
)
something like this should work, but you would also need to ensure its on the executor etc

It look like these are unique to a previous project.
Feel free to merge and ill introduce these later when I add windows support.
