[SYCL-WEB] Sync VTable related customization with sycl branch

[jsji]

Fixed CodeGenSYCL/virtual-types.cpp

[jsji]

This is exposed after -DINTEL_SYCL_OPAQUEPOINTER_READY=1, I am not sure this update is right, can someone familiar with it have a look and fix it? Maybe we some code previously guarded with #ifdef INTEL_SYCL_OPAQUEPOINTER_READY was wrong. Thanks.

@AlexeySachkov @elizabethandrews @jyu2-git Synced with sycl branch, the change now can get the test pass without changing addrspace. I think we can use this version first, while @jyu2-git working on the changes related to https://reviews.llvm.org/D153092 . What do you think? Thanks!

I am ok with this. SYCL branch was different from community clang here previously as well. So I don't see any (additional) harm.
