[SYCL] Ignore unknown users of virtual functions instead of crashing
The SYCLVirtualFunctionsAnalysis pass was crashing (calling llvm_unreachable) when it encountered a non-constant non-global use of an indirectly callable function.
Instead of that just ignore any user we don't know how to handle and log a debug message. The LLVM User hierarchy is mostly closed, so in practice the ignored users are mostly going to be instructions.
