intel-graphics-compiler: LLVM 13 fixes

[zboszor]

Also add CXXFLAGS=-Wno-error=deprecated-declarations, to turn some deprecated LLVM API usage from warnings to errors.

Fixes #3

looks good. I have forwarded it to meta-intel upstream directly. If its not accepted we will apply it to our fork.

I sent it to the proper mailing list but in the meantime it turned out it's not enough to get everything build with LLVM 13. opencl-clang needs a version 13.0.0 recipe from the ocl-open-130 branch, which in turn seems to need https://github.com/intel/opencl-clang/pull/273 I will experiment further on Monday.

The new IGC version seems to need more recipe changes, it fails in do_configure :(

[zboszor]

The new IGC version now compiles but still fails to build intel-compute-runtime with LLVM 13

I am carrying https://github.com/YoeDistro/meta-intel/commit/f36dea1c17b75b3245694582efff96a00b4d6ffd in yoe/mut do we still need this ?

It was an experiment on my side, still fails to build. I abandoned this PR and let the Intel guys to solve their stuff. They seem to be progressing.

This seems to compile now with the current latest commits from vc-intrinsics, IGC and compute-runtime. I haven't tested correct operation yet.

ocloc still crashes when run via qemuwrapper when compiling compute-runtime without -DNEO_DISABLE_BUILTINS_COMPILATION=1. Manual run shows this backtrace without source lines:

Maybe a newer release/13.x is required in meta-clang? I saw two crash fixes there that may or may not fix the crash in compute-runtime. @kraj
