Davide Italiano c2e69eb3d3 [CodeGen] Update test after recent changes in llvm (r293846).

Artem Belevich d40c9d5c5a Allow linking multiple bitcode files. 
Linking options for particular file depend on the option that specifies the file.
Currently there are two:

* -mlink-bitcode-file links in complete content of the specified file.
* -mlink-cuda-bitcode links in only the symbols needed by current TU.
   Linked symbols are internalized. This bitcode linking mode is used to
   link device-specific bitcode provided by CUDA.

Files are linked in order they are specified on command line.

-mlink-cuda-bitcode replaces -fcuda-uses-libdevice flag.

Artem Belevich 4eac4cf5a9 Fixed double-free in case of module loading error. 
GetOutputStream() owns the stream it returns pointer to and the
pointer should never be freed by us. When we fail to load and exit
early, unique_ptr still holds the pointer and frees it which leads to
compiler crash when CompilerInstance attempts to free it again.

Added regression test for failed bitcode linking.

Rafael Espindola b3dff4d84d Make this test a bit stricter by checking clang's output too.

Stephen Lin 93ab6bf534 CHECK-LABEL-ify some code gen tests to improve diagnostic experience when tests fail.

Rafael Espindola 96e7813f08 Add 'not' to commands that are expected to fail. 
This is at least good documentation, but also opens the possibility of
using pipefail.

Peter Collingbourne 22a7dfea58 Add support for lazily linking bitcode files (using a new 
-mlink-bitcode-file flag), and more generally llvm::Modules, before
running optimisations.
