BTW, mesa lists this as the LLVM version requirements:

LLVM_REQUIRED_GALLIUM=3.3.0
LLVM_REQUIRED_OPENCL=3.6.0
LLVM_REQUIRED_R600=3.8.0
LLVM_REQUIRED_RADEONSI=3.8.0
LLVM_REQUIRED_RADV=3.9.0
LLVM_REQUIRED_SWR=3.9.0

I'm not exactly sure what in gallium only needs LLVM 3.3, but it looks
to me like we need at least 3.8 and that would limit us to Android N
and later for enabling LLVM. Is that a correct assumption for
android-x86? We are only talking about what current mesa master
supports here.
