Build: disable address sanitizer for Cycles optimized kernels with GCC
It's extremely slow to compile and run, so just disable it unless
WITH_CYCLES_KERNEL_ASAN is manually enabled. For Clang it's always
enabled since that appears to work ok.
This also limits the -fno-sanitize=vptr flag to the Cycles kernel, as it
was added specifically to work around an issue there.
