undefined reference to `llvm::SimplifyExtractElementInst(llvm::Value*, llvm::Value*, llvm::SimplifyQuery const&)'

Building the DPC++ toolchain shows the following error. Could you reproduce the error ? Thank you.

Hi @zjin-lcf, the same error was reported in #3142.

I think as a short-term workaround you can revert #3127 locally

@asidoren-intel , can you please take a look?
Note, the build fails in the shared libs configuration. To reproduce add --shared-libs to the configure.py script.

I checked that the simple change in vc-intrinsics repo resolves the issue, but I leave the decision on the final fix for @asidoren-intel :

I submitted a PR with the fix here: intel/vc-intrinsics#49
