[Beignet] [PATCH] LLVM/Clang 3.7 compatibility

I have modified some files to allow beignet to compile with the current
git version of LLVM. I ran the utests with the -a option on an Intel HD
4000 and had mostly
successes except for

builtin_pow()
compiler_function_qualifiers()
test_load_program_from_spir()

Those are probably unrelated to the changes I made, but I haven't tested
with a lower llvm version.

I'm not sure about how to deal with the changes in ocl_mem*.ll, but for
everything in cpp code I used version guards.

The old pass managers moved to llvm/IR/LegacyPassManager.h, I have used
those and had to use some pass wrappers.

LLVMLinkerPreserveSource was removed, The value is still in the enum as
LLVMLinkerPreserveSource_Removed, but it has no effect.

>From llvm release notes: "The DataLayout is no longer optional. All the
IR level optimizations expects it to be present and the API has been
changed to use a reference instead of a pointer to make it explicit. The
Module owns the datalayout and it has to match the one attached to the
TargetMachine for generating code.". I'm not sure if that's the right
way to do this, but I passed the DataLayout from the runModulePass
function to createLoadStoreOptimizationPass() and removed addition of
DataLayout passes everywhere.

There was also a typo in llvm_to_gen.cpp: runFuntionPass -> runFunctionPass
