`opencl-c-base.h` always defines 5 particular feature macros for SPIR-V, making it impossible to disable those features. To allow disabling any of those features, let the header recognize `__undef_<feature>` macros. The user can then pass the `-D__undef_<feature>` flag on the command line to disable a specific feature. The __undef macro could potentially also be set from `-cl-ext=-feature`, but for now only change the header and only provide __undef macros for the 5 features that are always enabled in `opencl-c-base.h`.
