Change attribute((option(...))) to attribute((target(...))); Do not allocate tree nodes on x86 for builtins until we generate code for the ISA; Delete hot/cold functions changing optimization; Make C++ support target specific functions; Add #pragma GCC {push_options,pop_options,reset_options} instead of #pragma GCC {target,optimize} {push,reset,pop}
