Let's turn this on. :)

I thought we could remove all the LLVM goo from the CMake build system,
but I see there is some code to support LLVM for the EFL port on
AArch64. (For the GTK port, FTL is only supported on x86_64).

Do we want to continue to support FTL on AArch64 using LLVM, or do we
want to just turn off FTL on that platform until B3 is ready? It's
currently disabled by default, so I don't see much value in keeping it
around.
