Justin Lebar 066494d8c1 [CUDA] Print an error if you try to compile with < sm_30 on CUDA 9.
Summary:
CUDA 9's minimum sm is sm_30.

Ideally we should also make sm_30 the default when compiling with CUDA
9, but that seems harder than it should be.

Artem Belevich 8af4e23d1e [CUDA] Added rudimentary support for CUDA-9 and sm_70.
For now CUDA-9 is not included in the list of CUDA versions clang
searches for, so the path to CUDA-9 must be explicitly passed
via --cuda-path=.

On LLVM side NVPTX added sm_70 GPU type which bumps required
PTX version to 6.0, but otherwise is equivalent to sm_62 at the moment.

Justin Lebar d9bc485cfe [CUDA] Fix "control reaches end of non-void function" warnings in Cuda.cpp.
Some compilers are too dumb to realize that the switch statement covers
all cases.

(Don't use a "default" label, because we explicitly want to get a warning
if our switch doesn't cover all the cases.)

Justin Lebar 629076178a [CUDA] Add utility functions for dealing with CUDA versions / architectures.
Summary:
Currently our handling of CUDA architectures is scattered all around
clang.  This patch centralizes it.

A key advantage of this centralization is that you can now write a C++
switch on e.g. CudaArch and get a compile error if you don't handle one
of the enum values.
