Justin Lebar 25c4a81e79 [CUDA] Remove three obsolete CUDA cc1 flags. 
Summary:
* -fcuda-target-overloads

  Previously unconditionally set to true by the driver.  Necessary for
  correct functioning of the compiler -- our CUDA headers wrapper won't
  compile without this.

* -fcuda-disable-target-call-checks

  Previously unconditionally set to true by the driver.  Necessary to
  compile almost any external CUDA code -- almost all libraries assume
  that host+device code can call host or device functions.

* -fcuda-allow-host-calls-from-host-device

  No effect when target overloading is enabled.

Artem Belevich 9674a64cd9 [CUDA] Add appropriate host/device attribute to builtins. 
The changes are part of attribute-based CUDA function overloading (D12453)
and as such are only enabled when it's in effect (-fcuda-target-overloads).

Artem Belevich 7230a22d5e Revert r245496 "[CUDA] Add appropriate host/device attribute to builtins." 
It's breaking internal test.

Eli Bendersky f2787a0dc0 CUDA: mark the target of implicit intrinsics properly 
r218624 implemented target inference for implicit special members. However,
other entities can be implicit - for example intrinsics. These can not have
inference running on them, so they should be marked host device as before. This
is the safest and most flexible setting, since by construction these functions
don't invoke anything, and we'd like them to be invokable from both host and
device code. LLVM's intrinsics definitions (where these intrinsics come from in
the case of CUDA/NVPTX) have no notion of target, so both host and device
intrinsics can be supported this way.
