Dimitry Andric d849f8fd8f Fix XRayTest link on FreeBSD (and likely NetBSD too) 
Summary:
As reported on llvm-testers, during 8.0.0-rc1 testing I got errors while
building of `XRayTest`, during `check-all`:

```
[100%] Generating XRayTest-x86_64-Test
/home/dim/llvm/8.0.0/rc1/Phase3/Release/llvmCore-8.0.0-rc1.obj/./lib/libLLVMSupport.a(Signals.cpp.o): In function `llvm::sys::PrintStackTrace(llvm::raw_ostream&)':

```

This is because the `backtrace` function requires `-lexecinfo` on BSD
platforms.  To fix this, detect the `execinfo` library in
`cmake/config-ix.cmake`, and add it to the unit test link flags.

Additionally, since the code in `sys::PrintStackTrace` makes use of
`itaniumDemangle`, also add `-lLLVMDemangle`.  (Note that this is more
of a general problem with libLLVMSupport, but I'm looking for a quick
fix now so it can be merged to the 8.0 branch.)
