Hi, @andykaylor @bader @vzakhari
This PR includes:

  1. Add llvm float point intrinsic support in llvm-spirv
  2. Enable corresponding builtin in SemaSYCL
    This patch is ported from Andy's work and should fix std::complex issue on Windows platform.
    Thanks very much.

@jinge90, please, commit llvm-spirv translator changes here: https://github.com/KhronosGroup/SPIRV-LLVM-Translator/. They will be pulled to this repository.

I think we should move "supported" function out of "unsupported-math.cpp" test.

Moved the "supported" math builtin/function into a new case "supported_math.cpp".

Hi, @bader
Should I close this PR and commit the llvm-spirv translator change into https://github.com/KhronosGroup/SPIRV-LLVM-Translator/ firstly, then create a new PR in intel/llvm to enable the corresponding builtin when the llvm-spirv change is pulled into intel/llvm?
Thanks very much.

No. Clang and llvm-spriv parts are independent, so just move llvm-spirv patch from this PR to https://github.com/KhronosGroup/SPIRV-LLVM-Translator/.

OK,I will move the llvm-spirv part to another patch,commit to SPIRV-LLVM-Translator repo and only keep clang change in this PR.
Thanks very much!

This looks good to me. I think Alexey's suggestion to move the supported builtins to a separate test makes sense.

Hi, @andykaylor
I updated the patch to move supported builtins to a separate test but missed your previous approval, could you help review again?
Thanks very much.

This looks good to me, but, formally, clang code owners should review.
