to globally be controlled. Individual targets (e.g. ExceptionDemo) can
still override this by using LLVM_REQUIRE_RTTI and LLVM_REQUIRE_EH if
they need to be compiled with RTTI or exception handling respectively.

Both zero cost example domain specific, and C++ foreign exception handling are
shown. The example's documentation fully explains how to run the example.
Notes:
1) The code uses an extremely simple type info model.
2) Only a single landing pad is used per unwind edge
(one call to llvm.eh.selector)
3) llvm.eh.selector support for filter arguments is not given.
4) llvm.eh.typeid.for is not used.
5) Forced unwind behavior is not supported.
6) Very little if any error handling is given.
7) __attribute__((__aligned__)) is used.
8) The code uses parts from the llvm compiler-rt project and
the llvm Kaleidoscope example.
9) The code has not been ported or tested on WINDOWS.
10) The code was not tested with a cmake build.
11) The code was tested for a debug build on 32bit X86 CentOS LINUX,
and both a debug and release build on OS X 10.6.2 (64bit).
