Hi Cristophe,

I'm adding Greg, since he made it work a while ago. I remember he
added a few options to CMake and LIT to run the tests on an emulator
(basically QEMU), but I'm not sure all the cases were covered and
everything was working.

Meanwhile, can you build that natively on AArch64? I remember I've ran
all compiler-rt tests on AArch64, including the sanitizers, last
March. The results were encouraging... :)
